i686-pc-linux, gcc 2.95.2, binutils 2.9.1
>Description:
I tried building egcs-20000626 with gcc-2.95.2:

configure --enable-languages=c,c++ --enable-haifa \
 --with-cpu=i686 --enable-libstdcxx-v3 --enable-namespaces \
 --enable-threads=posix --enable-shared

File `libstdc++-v3/src/locale.cc' won't compile:

Only warnings (not critical as far as I can tell),
but `-Werror' makes it fail...
