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.

+! { dg-do compile }
+! Tests the fix for PR39295, in which the check of the interfaces
+! at lines 26 and 43 failed because opfunc1 is identified as a 
+! function by usage, whereas opfunc2 is not. This testcase checks
+! that TKR is stll OK in these cases.
