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.

+
+// This file provides the following:
+//
+// 1)  VERIFY(), via _GLIBCXX_ASSERT, from Brent Verner <brent@rcfile.org>.
+//   This file is included in the various testsuite programs to provide
+//   #define(able) assert() behavior for debugging/testing. It may be
+//   a suitable location for other furry woodland creatures as well.
+//
+// 2)  set_memory_limits()
+//   set_memory_limits() uses setrlimit() to restrict dynamic memory
+//   allocation.  We provide a default memory limit if none is passed by the
+//   calling application.  The argument to set_memory_limits() is the
+//   limit in megabytes (a floating-point number).  If _GLIBCXX_RES_LIMITS is
+//   not #defined before including this header, then no limiting is attempted.
+//
+// 3)  object_counter
+//   This is a POD with a static data member, object_counter::count,
+//   which starts at zero, increments on instance construction, and decrements
+//   on instance destruction.  "assert_count(n)" can be called to VERIFY()
+//   that the count equals N.
+//
+// 4)  copy_tracker, from Stephen M. Webb <stephen@bregmasoft.com>.
+//   A class with nontrivial ctor/dtor that provides the ability to track the
+//   number of copy ctors and dtors, and will throw on demand during copy.
