make just defaults CC to cc so setting CC in the surrounding environment works as intended, even without a Makefile. Just try: "CC=clang make foo" with a foo.c in the directory. There are however packages that explicitly set CC (to gcc) and other variables in the Makefile which is very annoying and IMO a bug. Timo
