Just a note re: the commit message, though: I wrote the patch to fix the error from comment #8; I'd assume the warnings I mentioned in comment #11 and comment #12 would still be an issue on darwin 10, though... I tried testing to confirm, but I'm actually currently knocked back to darwin 9 here, which has an older cctools and assembler, so now I error out earlier with an assembler error: Making all in c++98 make[6]: Entering directory `/private/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src/c++98' /bin/sh ../../libtool --tag CXX --tag disable-shared --mode=compile /var/root/gcc-git/my_oddly_named_builddir/./gcc/xgcc -shared-libgcc -B/var/root/gcc-git/my_oddly_named_builddir/./gcc -nostdinc++ -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src/.libs -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/libsupc++/.libs -B/usr/local/i386-apple-darwin9.8.0/bin/ -B/usr/local/i386-apple-darwin9.8.0/lib/ -isystem /usr/local/i386-apple-darwin9.8.0/include -isystem /usr/local/i386-apple-darwin9.8.0/sys-include -I/var/root/gcc-git/libstdc++-v3/../libgcc -I/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/include/i386-apple-darwin9.8.0 -I/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/include -I/var/root/gcc-git/libstdc++-v3/libsupc++ -std=gnu++98 -prefer-pic -D_GLIBCXX_SHARED -fno-implicit-templates -fvtable-verify=std -Wl,-u,_vtable_map_vars_start -Wl,-u,_vtable_map_vars_end -Wall -Wextra -Wwrite-strings -Wcast-qual -Wabi -fdiagnostics-show-location=once -fvisibility-inlines-hidden -ffunction-sections -fdata-sections -frandom-seed=bitmap_allocator.lo -g -O2 -c -o bitmap_allocator.lo ../../../../../libstdc++-v3/src/c++98/bitmap_allocator.cc libtool: compile: /var/root/gcc-git/my_oddly_named_builddir/./gcc/xgcc -shared-libgcc -B/var/root/gcc-git/my_oddly_named_builddir/./gcc -nostdinc++ -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src/.libs -L/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/libsupc++/.libs -B/usr/local/i386-apple-darwin9.8.0/bin/ -B/usr/local/i386-apple-darwin9.8.0/lib/ -isystem /usr/local/i386-apple-darwin9.8.0/include -isystem /usr/local/i386-apple-darwin9.8.0/sys-include -I/var/root/gcc-git/libstdc++-v3/../libgcc -I/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/include/i386-apple-darwin9.8.0 -I/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/include -I/var/root/gcc-git/libstdc++-v3/libsupc++ -std=gnu++98 -D_GLIBCXX_SHARED -fno-implicit-templates -fvtable-verify=std -Wl,-u,_vtable_map_vars_start -Wl,-u,_vtable_map_vars_end -Wall -Wextra -Wwrite-strings -Wcast-qual -Wabi -fdiagnostics-show-location=once -fvisibility-inlines-hidden -ffunction-sections -fdata-sections -frandom-seed=bitmap_allocator.lo -g -O2 -c ../../../../../libstdc++-v3/src/c++98/bitmap_allocator.cc -fno-common -DPIC -D_GLIBCXX_SHARED -o bitmap_allocator.o /var/tmp//ccxrd6Je.s:15603:FATAL:symbol: __ZN4_VTVIN9__gnu_cxx24__concurrence_wait_errorEE12__vtable_mapE can't be a weak_definition (currently only supported in section of type coalesced) make[6]: *** [bitmap_allocator.lo] Error 1 make[6]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src/c++98' make[5]: *** [all-recursive] Error 1 make[5]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3/src' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3' make[3]: *** [all] Error 2 make[3]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir/i386-apple-darwin9.8.0/libstdc++-v3' make[2]: *** [all-stage1-target-libstdc++-v3] Error 2 make[2]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/private/var/root/gcc-git/my_oddly_named_builddir' make: *** [all] Error 2 I get the feeling it could actually be related to those linker warnings I mentioned previously?
