Quoting a message Ronald wrote a few days back, when we were  
discussing universal builds:

"Python's configure has hardcoded that OSX 10.2 and 10.4 must not  
have _POSIX_SOURCE and friends defined. Annoyingly this means that if  
you build Python on Panther you'll have to patch the build if you  
want to build extensions on Tiger."

In other words, on Tiger and Jaguar, Python does not define  
_POSIX_C_SOURCE, in which case everything goes smoothly. I didn't  
remember this point until Bob mentioned the patch...

Actually, if Python can get along without having _POSIX_C_SOURCE  
defined, then removing that define from Python itself is a very good  
idea. However, you're right that it only solves the immediate  
problem, still leaving the problem that wx cannot be built when  
_POSIX_C_SOURCE is defined.

Thanks,

Kevin
