When building libstdc++-v3-3.3.4 on a system with gcc-3.4.x, the build will fail if -fweb is included in one's CFLAGS, since this flag is not supported on gcc-3.3.4. Reproducible: Always Steps to Reproduce: 1. emerge gcc-3.4.x 2. Add -fweb to your CFLAGS 3. emerge libstdc++-v3-3.3.4 Actual Results: checking whether the C compiler ( /var/tmp/portage/libstdc++-v3-3.3.4/work/build/gcc/xgcc -B/var/tmp/portage/libstdc++-v3-3.3.4/work/build/gcc/ -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -isystem /usr/i686-pc-linux-gnu/include -O2 -O2 -march=pentium4 -pipe ) works... no configure: error: installation or configuration problem: C compiler cannot create executables. make: *** [configure-target-libiberty] Error 1 !!! ERROR: sys-libs/libstdc++-v3-3.3.4 failed. !!! Function src_compile, Line 230, Exitcode 2 !!! (no error message) !!! If you need support, post the topmost build error, NOT this status message. This is essentially the same bug as 64252. The fix is to add -fweb to the list of filtered flags. Manually removing this flag allows build to complete.
