[PATCH] Cygwin: Add spawn family of functions to docs

[Mark Geisert]

In the doc tree, change the title of section "Other UNIX system
interfaces..." to "Other system interfaces...".  Add the spawn family of
functions noting their origin as Windows.

The title change seems warranted as neither the spawn family of
functions nor the listed clock_setres() function originated from UNIX
systems.
