+# This Makefile is intended only for DJGPP use.
+# It is mainly a copy of the main Makefile, but tends to get out of sync
+# with it.  A merge would probably be appropriate.
+
+# Primary targets:
+# gc.a - builds basic library
+# libgc.a - builds library for use with g++ "-fgc-keyword" extension
+#	    -fgc-keyword was never really available.  Historical
+#	    interest only.
+# c++ - adds C++ interface to library
+# cords - adds cords (heavyweight strings) to library
+# test - prints porting information, then builds basic version of gc.a,
+#      	 and runs some tests of collector and cords.  Does not add cords or
+#	 c++ interface to gc.a
+# cord/de$(EXE_SUFFIX) - builds dumb editor based on cords.

+CFLAGS= -gstabs+ -O2 -I$(srcdir)/include -DATOMIC_UNCOLLECTABLE -DNO_SIGNALS -DALL_INTERIOR_POINTERS -DNO_EXECUTE_PERMISSION -DSILENT
+
+# Setjmp_test may yield overly optimistic results when compiled
+# without optimization.
+# -DSILENT disables statistics printing, and improves performance.
+# -DFIND_LEAK causes GC_find_leak to be initially set.
+#   This causes the collector to assume that all inaccessible
+#   objects should have been explicitly deallocated, and reports exceptions.
+#   Finalization and the test program are not usable in this mode.
+# -DALL_INTERIOR_POINTERS allows all pointers to the interior
+#   of objects to be recognized.  (See gc_priv.h for consequences.)
+# -DSMALL_CONFIG tries to tune the collector for small heap sizes,
+#   usually causing it to use less space in such situations.
+#   Incremental collection no longer works in this case.
+# -DLARGE_CONFIG tunes the collector for unusually large heaps.
+#   Necessary for heaps larger than about 500 MB on most machines.
+#   Recommended for heaps larger than about 64 MB.
+# -DDONT_ADD_BYTE_AT_END is meaningful only with
+#   -DALL_INTERIOR_POINTERS.  Normally -DALL_INTERIOR_POINTERS
+#   causes all objects to be padded so that pointers just past the end of
+#   an object can be recognized.  This can be expensive.  (The padding
+#   is normally more than one byte due to alignment constraints.)
+#   -DDONT_ADD_BYTE_AT_END disables the padding.
+# -DNO_SIGNALS does not disable signals during critical parts of
+#   the GC process.  This is no less correct than many malloc 
+#   implementations, and it sometimes has a significant performance
+#   impact.  However, it is dangerous for many not-quite-ANSI C
+#   programs that call things like printf in asynchronous signal handlers.
+#   This is on by default.  Turning it off has not been extensively tested with
+#   compilers that reorder stores.  It should have been.
+# -DNO_EXECUTE_PERMISSION may cause some or all of the heap to not
+#   have execute permission, i.e. it may be impossible to execute
+#   code from the heap.  Currently this only affects the incremental
+#   collector on UNIX machines.  It may greatly improve its performance,
+#   since this may avoid some expensive cache synchronization.
+# -DGC_NO_OPERATOR_NEW_ARRAY declares that the C++ compiler does not support
+#   the  new syntax "operator new[]" for allocating and deleting arrays.
+#   See gc_cpp.h for details.  No effect on the C part of the collector.
+#   This is defined implicitly in a few environments.  Must also be defined
+#   by clients that use gc_cpp.h.
+# -DREDIRECT_MALLOC=X causes malloc, realloc, and free to be defined
+#   as aliases for X, GC_realloc, and GC_free, respectively.
+#   Calloc is redefined in terms of the new malloc.  X should
+#   be either GC_malloc or GC_malloc_uncollectable.
+#   The former is occasionally useful for working around leaks in code
+#   you don't want to (or can't) look at.  It may not work for
+#   existing code, but it often does.  Neither works on all platforms,
+#   since some ports use malloc or calloc to obtain system memory.
+#   (Probably works for UNIX, and win32.)
+# -DIGNORE_FREE turns calls to free into a noop.  Only useful with
+#   -DREDIRECT_MALLOC.
+# -DNO_DEBUGGING removes GC_dump and the debugging routines it calls.
+#   Reduces code size slightly at the expense of debuggability.
+# -DJAVA_FINALIZATION makes it somewhat safer to finalize objects out of
+#   order by specifying a nonstandard finalization mark procedure  (see
+#   finalize.c).  Objects reachable from finalizable objects will be marked
+#   in a sepearte postpass, and hence their memory won't be reclaimed.
+#   Not recommended unless you are implementing a language that specifies
+#   these semantics.  Since 5.0, determines only only the initial value
+#   of GC_java_finalization variable.
+# -DFINALIZE_ON_DEMAND causes finalizers to be run only in response
+#   to explicit GC_invoke_finalizers() calls.
+#   In 5.0 this became runtime adjustable, and this only determines the
+#   initial value of GC_finalize_on_demand.
+# -DATOMIC_UNCOLLECTABLE includes code for GC_malloc_atomic_uncollectable.
+#   This is useful if either the vendor malloc implementation is poor,
+#   or if REDIRECT_MALLOC is used.
+# -DHBLKSIZE=ddd, where ddd is a power of 2 between 512 and 16384, explicitly
+#   sets the heap block size.  Each heap block is devoted to a single size and
+#   kind of object.  For the incremental collector it makes sense to match
+#   the most likely page size.  Otherwise large values result in more
+#   fragmentation, but generally better performance for large heaps.
+# -DPRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever
+#   the garbage collector detects a value that looks almost, but not quite,
+#   like a pointer, print both the address containing the value, and the
+#   value of the near-bogus-pointer.  Can be used to identifiy regions of
+#   memory that are likely to contribute misidentified pointers.
+# -DKEEP_BACK_PTRS Add code to save back pointers in debugging headers
+#   for objects allocated with the debugging allocator.  If all objects
+#   through GC_MALLOC with GC_DEBUG defined, this allows the client
+#   to determine how particular or randomly chosen objects are reachable
+#   for debugging/profiling purposes.  The gc_backptr.h interface is
+#   implemented only if this is defined.
+# -DGC_ASSERTIONS Enable some internal GC assertion checking.  Currently
+#   this facility is only used in a few places.  It is intended primarily
+#   for debugging of the garbage collector itself, but could also
+# -DDBG_HDRS_ALL Make sure that all objects have debug headers.  Increases
+#   the reliability (from 99.9999% to 100%) of some of the debugging
+#   code (especially KEEP_BACK_PTRS).  Makes -DSHORT_DBG_HDRS possible.
+#   Assumes that all client allocation is done through debugging
+#   allocators.
+# -DSHORT_DBG_HDRS Assume that all objects have debug headers.  Shorten
+#   the headers to minimize object size, at the expense of checking for
+#   writes past the end of an object.  This is intended for environments
+#   in which most client code is written in a "safe" language, such as
+#   Scheme or Java.  Assumes that all client allocation is done using
+#   the GC_debug_ functions (or through the macros that expand to these.
+#   (Also eliminates the field for the requested object size.)
+#   occasionally be useful for debugging of client code.  Slows down the
+#   collector somewhat, but not drastically.
+# -DCHECKSUMS reports on erroneously clear dirty bits, and unexpectedly
+#   altered stubborn objects, at substantial performance cost.
+#   Use only for debugging of the incremental collector.
+# -DGC_GCJ_SUPPORT includes support for gcj (and possibly other systems
+#   that include a pointer to a type descriptor in each allocated object).
+#   Building this way requires an ANSI C compiler.
+# -DUSE_I686_PREFETCH causes the collector to issue Pentium III style
+#   prefetch instructions.  No effect except on X86 Linux platforms.
+#   Assumes a very recent gcc-compatible compiler and assembler.
+#   (Gas prefetcht0 support was added around May 1999.)
+#   Empirically the code appears to still run correctly on Pentium II
+#   processors, though with no performance benefit.  May not run on other
+#   X86 processors?  In some cases this improves performance by
+#   15% or so.
+# -DUSE_3DNOW_PREFETCH causes the collector to issue AMD 3DNow style
+#   prefetch instructions.  Same restrictions as USE_I686_PREFETCH.
+#   UNTESTED!!
+# -DGC_USE_LD_WRAP in combination with the gld flags listed in README.linux
+#   causes the collector some system and pthread calls in a more transparent
+#   fashion than the usual macro-based approach.  Requires GNU ld, and
+#   currently probably works only with Linux.
