I'm trying to build python 2.6 on a Mac OS X 10.3 system. This fails to
build the multiprocessing extension due to a missing definition of "struct
iovec".

It turns out that you have to include <sys/uio.h> to get that definition
on OSX 10.3.

Adding '#include <sys/uio.h>' to multiprocessing.h enables building the
extension on OSX 10.3, but is probably not the right solution.

[loewis]

What does sendmsg(2) say what to include? What about writev(2)? (the
latter, on Linux, says that sys/uio.h is indeed the correct header)

[ronaldoussoren]

The manpage for writev(2) mentions #include <sys/uio.h>. Adding a #include
for <sys/uio.h> is the right fix after all...
