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 package provides the basic computational interface for the generic
+--  elementary functions. The C library version interfaces with the routines
+--  in the C mathematical library, and is thus quite portable, although it may
+--  not necessarily meet the requirements for accuracy in the numerics annex.
+--  One advantage of using this package is that it will interface directly to
+--  hardware instructions, such as the those provided on the Intel x86.
+
+--  Note: there are two versions of this package. One using the 80-bit x86
+--  long double format (which is this version), and one using 64-bit IEEE
+--  double (see file a-numaux.ads).
