Sorry, my mistake - I should have said that you need to put 'CC=gcc-3.0'
on make's command line, rather than in the environment. For instance:

	[cjwatson@arborlon ~]$ cat test.mk 
	CC = gcc
	all:
		echo $(CC)
	[cjwatson@arborlon ~]$ make -f test.mk
	echo gcc
	gcc
	[cjwatson@arborlon ~]$ make -f test.mk CC=gcc-3.0
	echo gcc-3.0
	gcc-3.0

This will work unless somebody has used an 'override' command in the
Makefile, but fortunately that's very rare.
