Could you check whether the CFLAGS and CXXFLAGS in the generated GNUmakefile contain the options you've additionally specified?
There are at least two ways of doing this: - `cat GNUmakefile | grep "^CFLAGS"; cat GNUmakefile | grep "^CXXFLAGS"`, - run `make V=1` and see that the compiler invocations are using the specified options.
