Do we need getpwuid_r?

[walt <wa1ter@xxxxxxxxxxxxx>]

I see that linux, NetBSD, and FreeBSD all have getpwuid_r in
<pwd.h>, but we don't.

I ask because the recent pkgsrc upgrade to gnome 2.16 fails,
and this seems to be the reason.  (As an aside, I see that
pwd.h on my linux machine is installed by the glibc package.)

Anyone know what's behind this difference?

Thanks!
