Like that: .if ${.CURDIR:M/usr/src} || ${.CURDIR:M/usr/src/*} CC=clang CXX=clang++ CPP=clang-cpp NO_WERROR= WERROR= .endif I had hoped that the .ifdef construction from the wiki was dated. I suppose it's emulating setting CC in the environment instead of in the make/src.conf. > Also, if you force CFLAGS to have -march=athlon64-sse3, I'm not > sure if the build32 stage can even work correctly.

I tried CC?=, but that doesn't work, because apparently make always initializes CC before parsing makefiles. I figure that means the !defined(CC) clause in the .ifdef construction is never true and thus obsolete. I didn't try it, though.
