I am seeing a new failure on x86_64-apple-darwin10 in current gcc 4.4 branch
that wasn't present in the gcc 4.4.0 release. At -m32, the testsuite failure...
FAIL: gcc.c-torture/compile/20000804-1.c -O0 (test for excess errors)
appears with the error logged as...

The failure doesn't occur at -m32 if I pass -fno-PIC on the compilation line.
Could someone with current gcc 4.4 branch
on x86_64-*-linux check to see if they get the same failure with -m32 -fPIC at
-O0 for gcc.c-torture/compile/20000804-1.c?
This looks like a regression from gcc 4.4.0.
