In that case, the user could still put the appropriate instructions
into Modules/Setup, which they'd probably do anyway, since they need
special -I/-L options. So I agree with the notion that setup.py should
only do so much autoconfiguration, and leave special cases to manual
configuration through Modules/Setup.

However, I dislike the frequent usage of platform in setup.py, where
this patch adds another instance of. I believe the autoconf approach
"test for features, not system names" is much more flexible. If the
curses module requires certain feature, find a way of testing whether
the features are present, and only compile _curses if they are. Then
it would not be necessary to check whether the system name is
"darwin1". This is problematic in particular as different spellings of
the platform are expected: It is "darwin1" in some places, and
"Darwin1.2" atleast in another place.
