I know it works for "./configure CC=gcc-4.3.2 ..." and I'm sorry to
hear it doesn't for C_INCLUDE_PATH.  The difference is undoubtedly
that config.status uses any CC override in the generated Makefiles but
not C_INCLUDE_PATH.  So to get it to work that way, you'd presumably
need to edit */Makefile.am to set C_INCLUDE_PATH if it is present.
