Comment (by kencu):

 Well, that's nice to hear.

 Honest truth is not many upstream projects are too interested in tweaking
 builds for compilers like gcc-4.2 any more, and working around things
 missing from the MacOSX Tiger headers even less, so we are fairly used to
 doing a little surgery on these ports for our rather dedicated legacy
 system user base.

 redefining typedefs was introduced in some compiler version > gcc-4.2 -- I
 don't recall just when it occurred -- but in the way MacPorts works, it's
 basically a built-in next compiler step to set the bar at C11 and that
 sets a generation of compilers that do work rather than doing a lot of
 experimenting to find out just exactly which version of gcc allowed it and
 then undertaking a project of blacklisting or fallbacking.

 Appreciate your interest.
