I wondered what VC would make of those. Is there a <sys/wait.h> file?

I suppose we have to just print the raw return value, which
unfortunately makes it harder for a user to determine why the command
failed. Can we at least assume that zero is success?

Looking at APR's Win32 implementation of apr_proc_wait for inspiration
I see that it doesn't even set the exitwhy return value. This could
be a problem, since on Unix subversion should really be checking that
before deciding that an exit status of zero indicates success.
