Sorry for the delay (Rosemary Elizabeth Sayle was born 2:08pm

The following patch adds a testcase for the recently fixed GNATS
PR c/7128.  I've tested that this PASSes with current mainline
on i686-pc-linux-gnu but FAILs without my recent patch.  Interestingly
this is only the second testcase to check for an undeclared identifier.
I've also checked that the __asm__ is portable by failing to compile
on alpha/Tru64, sparc/Solaris and parisc/HPUX.

Ok for mainline?
