Update of /cvsroot/python/python/dist/src/Include
In directory usw-pr-cvs1:/tmp/cvs-serv19023/python/Include
Modified Files:
pyport.h
Log Message:
Stop trying to cater to platforms with a broken HUGE_VAL definition. It
breaks other platforms (in this case, the hack for broken Cray systems in
turn caused failure on a Mac system broken in a different way).
