[MacPorts] #35148: gegl 0.2.0_0 Syntax error before 'AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER'

[Jeremy Huddleston Sequoia]

gcc-3.3 is ancient.  You should avoid using it.

Also, selecting a different compiler will not cause macros to magically appear in system headers.  The problem is that the project is using the availability macros, but those are not supposed to be used by third party projects.  Indeed, they only have meaning when used in system headers.  It doesn't make sense to add them to 3rd party headers because they just denote when something was added to the *system*.

I've commented as such in the gnome bug report and will give them a patch to address this immediate issue.
