When adding a workaround for bug 789708, I noticed the following in the only version in tree (2.5.15-r2) in src_configure: > # other flags will break duma > export CFLAGS="-O0 -Wall -Wextra -U_FORTIFY_SOURCE" It seems like it'd be better to use strip-flags from flag-o-matic if truly necessary, but that said, it seems unlikely we need -Wall -Wextra in order to compile. Or replace -O? with -O0, which is preferred, to allow e.g. arch specific FLAGS. Additionally, this package has some parts in C++, so at least for those components, CXXFLAGS is used: >x86_64-pc-linux-gnu-g++ -Wl,-O1 -Wl,--as-needed -Wl,--defsym=__gentoo_check_ldflags__=0 -O2 -pipe -march=native -fdiagnostics-color=always -frecord-gcc-switches -std=c++14 -fPIC -DPIC -DDUMA_SO_LIBRARY -c dumatestpp.cpp -o dumatestpp_so.o ... which isn't a problem per-se, but if the C code really needs -O0, it's not a far leap to think that maybe the C++ will too. It'd be worth updating the comment at least even if not.
