 I see. It doesn't seem to have been announced anywhere big time, so 
 missed that information. Sorry.
 
 While lang/gcc32 will build just fine without USE_GCC, the compiler used 
 in this case (cc) will complain a lot about GCC extensions being used. 
 So that's not a good idea. It seems to me that the following might be a 
 proper fix:
 
 bsd.gcc.mk should try to satisfy the USE_GCC with the system compiler 
 first and only if that does not match the version requested, it should 
 try port versions. This way, USE_GCC= 2.7+ would take on the same 
 meaning as the old USE_GCC= X in that it simply requests for system GCC 
 to be used. At the same time, things such as USE_GCC= 3.1 would continue 
 to work because if the system compiler isn't 3.1, bsd.gcc.mk would keep 
 looking for an acceptable GCC.
