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.

+# Break simple tests into two pieces and see that they work when linked
+# together.  If an alternate compiler is specified then the two main
+# pieces of each test are compiled with different compilers.  The

+# struct-layout-1 are generated structure layout interoperability tests,
+# so a generator first needs to be compiled on host, run there and the
+# generated tests then compiled on build and executed on target.
