Hi Jerry,

on x86-linux I'm seeing three regressions:

complex_inserters_extractors.exe: 
/home/paolo/Gcc/cvs-dirs/gcc-head/gcc/libstdc++-v3/testsuite/26_numerics/complex/complex_inserters_extractors.cc:96: 
void test01(): Assertion `str == "(-1.1,-333.2)"' failed.
FAIL: 26_numerics/complex/complex_inserters_extractors.cc execution test

1.exe: 
/home/paolo/Gcc/cvs-dirs/gcc-head/gcc/libstdc++-v3/testsuite/27_io/basic_ostream/inserters_arithmetic/char/1.cc:168: 
void test01(): Assertion `os && os.str() == tc.result' failed.
FAIL: 27_io/basic_ostream/inserters_arithmetic/char/1.cc execution test

1.exe: 
/home/paolo/Gcc/cvs-dirs/gcc-head/gcc/libstdc++-v3/testsuite/27_io/basic_ostream/inserters_arithmetic/wchar_t/1.cc:166: 
void test01(): Assertion `os && os.str() == tc.wresult' failed.
FAIL: 27_io/basic_ostream/inserters_arithmetic/wchar_t/1.cc execution test

In the first case, f.i., str == (-1.,-333.) instead of the expected value.

Thanks,
Paolo.
