obtained gcc-4.6.4.tar.bz2 from upstream website;upstream

verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.

downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.

if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

+@node Header Dirs
+@chapter Standard Header File Directories
+
+@code{GCC_INCLUDE_DIR} means the same thing for native and cross.  It is
+where GCC stores its private include files, and also where GCC
+stores the fixed include files.  A cross compiled GCC runs
+@code{fixincludes} on the header files in @file{$(tooldir)/include}.
+(If the cross compilation header files need to be fixed, they must be
+installed before GCC is built.  If the cross compilation header files
+are already suitable for GCC, nothing special need be done).
+
+@code{GPLUSPLUS_INCLUDE_DIR} means the same thing for native and cross.  It
+is where @command{g++} looks first for header files.  The C++ library
+installs only target independent header files in that directory.
+
+@code{LOCAL_INCLUDE_DIR} is used only by native compilers.  GCC
+doesn't install anything there.  It is normally
+@file{/usr/local/include}.  This is where local additions to a packaged
+system should place header files.
+
+@code{CROSS_INCLUDE_DIR} is used only by cross compilers.  GCC
+doesn't install anything there.
+
+@code{TOOL_INCLUDE_DIR} is used for both native and cross compilers.  It
+is the place for other packages to install header files that GCC will
+use.  For a cross-compiler, this is the equivalent of
+@file{/usr/include}.  When you build a cross-compiler,
+@code{fixincludes} processes any header files in this directory.
