This puzzles me.  It looks like you're missing sys/types.h when
including sys/signal,h, but sys/signal.h includes sys/types.h by
itself, prior to including cygwin/signal.h.

How can I reproduce this?  An STC like this:

  #include <signal.h>
  main () {}

is definitely not sufficient.


Thanks,
Corinna
