is it a good idea to overwrite GCC_DEFAULT_VERSION= in Mk/bsd.gcc.mk?

Hi Gerald,

I don't think this is working as expected. See also ports/177017 which I
believe is a bsd.gcc.mk issue and not a pkgng or portmaster issue. My
understanding is that this user want

When I change GCC_DEFAULT_VERSION to 4.7, it now depends on the gcc47
package, but still is using lang/gcc:
