Paolo,

Thanks for the quick reaction.

Well, there are some failures though.

E.g. 27_io/basic_ios/3.cc
/Volumes/xufs/gcc-cvs/gcc/libstdc++-v3/testsuite/27_io/basic_ios/3.cc:135: 
error
: expected unqualified-id^M
/Volumes/xufs/gcc-cvs/gcc/libstdc++-v3/testsuite/27_io/basic_ios/3.cc:135: 
error
: abstract declarator `long unsigned int' used as declaration^M
/Volumes/xufs/gcc-cvs/gcc/libstdc++-v3/testsuite/27_io/basic_ios/3.cc:135: 
error
: explicit instantiation of non-template `long unsigned int $_52'^M
compiler exited with status 1
output is:
/Volumes/xufs/gcc-cvs/gcc/libstdc++-v3/testsuite/27_io/basic_ios/3.cc:135: 
error
: expected unqualified-id^M
/Volumes/xufs/gcc-cvs/gcc/libstdc++-v3/testsuite/27_io/basic_ios/3.cc:135:

I had to add the removed part again, but modified:

	std::basic_streambuf<gnu_char_type>::int_type
   --> 	std::basic_filebuf<gnu_char_type>::_S_pback_size;

Also, I'm not quite sure if you can remove the std::xxxx; <----- semicolon

You're the c++ expert!

I continue for a moment, then I'm away for an hour or 2.

Thanks,
Andreas
