>Description:

When building gnome-libs on darwin, the build fails with a fatal
glib error when running gnome-gen-mimedb on pkg/etc/mime-magic:

  GLib-ERROR **: could not allocate -1 bytes
  aborting...

I tracked this to an error in glib when sysconf (_SC_GETPW_R_SIZE_MAX)
returns -1.  This bug is fixed for FreeBSD in patch-af from PR 21909
However, that patch is protected by #ifdeff __FreeBSD__ and so does
fix the problem seen by Darwin.

>How-To-Repeat:

build gnome-libs on darwin

>Fix:

I propose removing the __FreeBSD__ check in patch-af since this
patch is appropriate for any system where sysconf (_SC_GETPW_R_SIZE_MAX)
returns -1 and should not affect systems that implement this call.
