thanks, pushed.
a few comments:
- please give reasons (name missing symbols, etc.) for particular fixes.
  i've seen too many portability fixes which were suboptimal or plain
  bogus (just fixing the symptoms instead of the actual issues) to blindly
  trust any.
  though i was able to figure it out this time. :)
- don't add gratuitous #ifdefs. the SUSv3 man page clearly states that
  kill() needs signal.h.

diego: and no, one doesn't need to make a merge request for that. not
only copyright law, but just plain common sense tells that this cannot
be reasonaly expected for such things. ;)
