Or you can commit it directly as you wish since you've commit rights. But the 
patch are not strictly identical. I tested #ifdef MACOSX_FRAMEWORK whereas the 
link you provide test #ifdef __APPLE__ . Not sure if they are equivalent in 
the GDAL context. Perhaps #ifdef __APPLE__ is better and MACOSX_FRAMEWORK too 
specific to a special flavour of building a shared lib ? Just guessing 
blindly...
