Actually, for linux, that's supposed to be handled by this code in
stdenv.h:

  #ifdef linux
  #include "unistd.h"
  #define setpgrp(a, b)	setpgid(a, b)
  #endif

That's in the 0.9-alpha1 release, but wasn't in 0.84.  I'd probably
upgrade to the alpha release if I were you, but there are a couple of
needed patches which I've sent out to the list.

I want to put out an alpha2 release soon, indended to deal with
configuration issues.  The stdenv.h/config.h is just the wrong thing.
I'd love to use GNU autoconf, but want to keep es in the public domain
and not covered by the GPL.  Not that it really matters.

Should be fine.  Putting all those prototypes into the source was a
mistake.  This is part of that same configuration nightmare.
