 Hmm...
 I understand your position (surely shared by other developers)
 but this bugfixes come from gcc's stable branch and I will not
 go hunting for bugs in the ports tree that have already been
 reported in gcc GNATs.
 
 Some of the bugs don't affect building but at all but will have
 serious performance implications or will break debugging. 
 
 An example (both are bugs still in our base gcc):
 gcc PR tree-optimization/25413 is pretty serious as
 it means Pentium 4 SSE optimizations are broken.
 gcc PR tree-optimization/32723 is much less serious
 and code similar to the testcase is not easy to find
 in the ports tree (it compiles but uses a LOT of memory).
 
 I know that 25413 should be applied but it's ridiculous not
 to fix 32723 (which appears first in the changelog) just
 because it's not something people have noticed.
 
 Eventually people will notice these issues and will blame
 FreeBSD and not gcc... and I am starting to think they will
 be right to do so :(.
