I fixed the compilation, but the stuff in process.c needs work: if you
invoke "M-x grep", Emacs aborts after Grep exits, here:

  void
  delete_read_fd (int fd)
  {
    eassert (fd < MAXDESC);
    eassert (fd <= max_desc); <<<<<<<<<<<<<<<<<

because max_desc is zero.

In general, I'd be grateful if Someone(TM) could explain the main
changes in process.c, as it's pretty basic stuff, and some of the
changes would originally not even compile, because some variables
involved in the changes were declared conditionally.  Since I couldn't
grasp the rationale for the changes in the few minutes I had to spare,
I'm not sure I fixed the code correctly.

Finally, there's a warning in regex.c:

  regex.c: In function `re_set_whitespace_regexp':
  regex.c:1250: warning: assignment discards qualifiers from pointer target type

but I don't think it's Windows specific.

In sum, I'd say this branch still "needs work".

Thanks.
