Yes, a simple one. ;-)  I made the simplification to the lang/gcc4x
ports only a few months ago (mid-July) at which point the lang/gcc3x
were already in deep maintenance mode after upstream has abandoned
these for a while.

To be on the safe side, I am generally cautious which changes to the 
lang/gcc3x ports these days and thus did not apply these changes there
as well because they do not really seem to be too important.  If you
look at lang/gcc33 and lang/34, you'll see that we got increasingly
conservative with these two.

I put a bit of documentation related to this into the upstream GCC
installation documentation (see http://gcc.gnu.org/install/build.html
for example, search for CFLAGS).

In the context of the FreeBSD Ports Collection, I believe adding the
appropriate settings to the MAKE_ENV in lang/gccXY/Makefile should work.

Hope this helps,
Gerald
