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.

+// Test mangling of __float128.
+// The C++ ABI document says __float128 is mangled as "g".  It
+// also says that "long double" is mangled as "e", so these conflict on
+// ia64-hpux where "long double" is "e" and __float128 is synonymous with
+// "long double".
