Comment(by howarth@…):

 I added the patches to FSF gcc 4.4 branch and trunk to compile on
 darwin10. These were never back ported to the earlier FSF gcc releases.
 The FSF gcc 4.2 branch is now depreciated and the effort to backport all
 those changes to FSF gcc 4.3 branch didn't seem worth the effort. In fink,
 I marked their gcc42 and gcc43 packages as Distribution: 10.4,10.5 so that
 they don't get built on 10.6. MacPorts needs to do something like this.
 You can compile the gcc44 package in MacPorts on 10.6 if you use my
 proposed update in ticket 21341.
