[Pyobjc-dev] libffi on OSX 10.1

[Ronald O. <ous...@ci...>]

I got bored and installed 10.1.5 and the December 2001 developer tools 
on a spare partition. I then tried to build python and pyobjc. The 
former mostly succeeded (more on that on the MacPython list), but I ran 
into some problems with pyobjc.

First of all libffi won't build, seemingly due to a compiler bug:

I've continued building using the still existing non-ffi support, but 
that didn't fly either. I did get it to compile cleanly, but I get an 
segmentation fault when trying to import the objc module. I did not yet 
look into this.

My changes are in CVS.
