You're both fully correct; I have fooled myself once again:

$ echo $MANPATH
/usr/local/man:/usr/man:/usr/share/man:/usr/autotool/devel/man::/usr/ssl/man
:/cygdrive/e/Amiga/GG/man

$ man -W 2 getpriority
/cygdrive/e/Amiga/GG/man/man2/getpriority.2

This is manpages that comes with an old version of "geekgadgets"
(www.geekgadgets.org) - a project that reflects cygwin, but on/for AmigaOS.

Conclusion: Remember the above, or remove that last MANPATH-item. ,:-I

$ find /usr/include -type f | xargs grep -H PRIO_PROCESS
$
i.e. nothing...

Neither of you commented on this - which, for me, is a greater concern. I'm
not going to say that it is _important_, but I'd like to read some words
about it.
 e.g: Is this a "low priority" thing, doesn't Win have something that allows
an easy implementation, or...

 Googling on [gs]etpriority turns upp hits in glibc-hacker only. Nothing
cygwin related.

 Well, I obviously had my eyes more on the fact that there was a patch
removing/inserting PRIO_PROCESS into resources.h - not really checking WHERE
the google hits came from (as I had typed "site:cygwin.com" I didn't expect
deviations from that).
 Now I realize that both hits I got was rather irrelevant.

I'm taking "notes" :-) - thanks!

 Is there words about using google on "site:cygwin.com" in the FAQ or some
such? This note might need to be added there... (or a modified version).
