[Python-checkins] CVS: distutils/distutils unixccompiler.py,1.26,1.27

Update of /cvsroot/python/distutils/distutils
In directory slayer.i.sourceforge.net:/tmp/cvs-serv15000
Modified Files:
unixccompiler.py
Log Message:
Got rid of direct dependence on the sysconfig module. Mainly, this
meant playing along with the new "dictionary of executables" scheme
added to CCompiler by adding the 'executables' class attribute, and
changing all the compile/link/etc. methods to use the new attributes
(which encapsulate both the program to run and its standard arguments,
so it was a *little* bit more than just changing some names).
