I'd leave the Framework Makeconf alone. It is not enabled
by default because GCC is not guaranteed to be the compiler
for CC.

I'd recommend adding it to PKG_CFLAGS, PKG_CXXFLAGS,
and/or PKG_FFLAGS in your package's Makevars file while
developing the package and remove it prior to release.
Be aware R CMD check will start giving you nonportable
warnings; live with it unless you really feel like going
the configure script route.
