dnl First, we zap CFLAGS, FFLAGS and CXXFLAGS (unless explicitly set
dnl by the user). We then choose -O3 for gcc and -O for all other
dnl compilers, and no optimization for the debugging library.
dnl
dnl NOTE: we use 7 spaces to distinguish a user-override of "" from
dnl our internal hack. Personally, I'd prefer to leave the fiddling
dnl with the CFLAGS to the user. Mmmh.
