It is supposed to do that, but to be honest I don't remember if the  
code for that is present in the 2.3 tree and I'm too lazy to check the  
sources right now.

The deployment target does have an influence on how the compiler  
functions, which can explain when setting the target to a different  
value causes problems.

In current versions of python this is read from config/Makefile in the  
standard library (that is /Library/Frameworks/Python.framework/ 
Versions/2.3/lib/python2.3/config/Makefile)
