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.

+! Some basic testing that calls to the library still work correctly with
+! -ff2c
+!
+! Once the library has support for f2c calling conventions (i.e. passing
+! a REAL(kind=4) or COMPLEX-valued intrinsic as procedure argument works), we
+! can simply add -ff2c to the list of options to cycle through, and get
+! complete coverage.  As of 2005-03-05 this doesn't work.
