You may need to set $CCC_CC and/or $CCC_CXX, especially if you're using
cross compilers or something like that. When you run scan-build it will
make sure that those compilers are put into $CC and $CXX respectively.

Similarly, if your makefile ignores $CC/$CXX, I don't think scan-build
will do what you want. It needs to replace the compiler you're using
with a wrapper.
