AFAIK it doesn't, and a quick look at the documentation reveals nothing
so you're probably right. This has always been done by a higher level
tool than the compiler - there's no real need for the compiler to know
about it, and it would probably lead to counterintuitive results if you
forgot you had the environment variables set.
You could still use environment variables if you used make - it has a
number of default rules which will be filled in using them if they're
not in the makefile (and IIRC override the Makefile), so if you say
something like
export CC=echo
make foo
and there's a foo.c it will try to build foo from foo.c using a command
like
$(CC) $(CFLAGS) foo.c -o foo
Take a look at the manual for make - it can probably do what you want
even if you don't write a makefile. If it doesn't, a shell script wrapper
around cc probably will.
