------- Comment #6 from dominiq at lps dot ens dot fr 2008-01-14 16:15 ------- If I go back to my default config:
../gcc-4.3-work/configure --prefix=/opt/gcc/gcc4.3w --mandir=/opt/gcc/gcc4.3w/share/man --infodir=/opt/gcc/gcc4.3w/share/info --build=i686-apple-darwin9 --enable-languages=c,c++,fortran,objc,obj-c++,java --with-gmp=/sw --with-libiconv-prefix=/usr --with-system-zlib --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib the -Werror is no longer there when building libstdc++-v3 and I have been able to build it, though I stll have the warning about "'unsigned int size_of_encoded_value(unsigned char)' defined but not used". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34780
