Correct, but the spawn module I posted should work for any case where
you want to run an external command synchronously without redirecting
I/O. (And it could probably be extended to handle those cases, but a) I
don't need them for Distutils [yet!], and b) I don't know how to do it
portably.)

[off-topic alert... probably belongs on distutils-sig, but there you go]
Yes, my CCompiler class is all about providing a (hopefully) compiler-
and platform-neutral interface to a C/C++ compiler. Currently there're
only two concrete subclasses of this: UnixCCompiler and MSVCCompiler,
and they both obviously use spawn, because Unix C compilers and MSVC
both provide that kind of interface. A hypothetical sibling class that
provides an interface to some Mac C compiler might use a souped-up spawn
that "knows about" Apple Events, or it might use some other interface to
Apple Events. If Jack's simplified summary of what passing Apple Events
to a command looks like is accurate, maybe spawn can be souped up to
work on the Mac. Or we might need a dedicated module for running Mac
programs.
So does anybody have code to run external programs on the Mac using
Apple Events? Would it be possible/reasonable to add that as
'_spawn_mac()' to my spawn module?
