USE_GCC is the right statement, but one should be careful about adding such
statements to make.conf without conditions, because you can pollute every
invocation of make(1). Here, you can cause cycles in your dependency graphs
if you set USE_GCC=4.6 for any of the ports that are required by lang/gcc46.
If you are interested in applying them to a single port, use a test on .CURDIR,
or, better yet, add the statement to any of the optional Makefiles that are
automatically included by bsd.port.mk and were intended for that purpose --
${MASTERDIR}/Makefile.local, for example. Please be careful in what you add,
or recommend that others add, to make.conf.
