With Dieter's response I was able to modify my config.status file to get
past this issue.  There are already issues open in the tracker items for
MinGW to add atomic support as well as MemoryBarrier.  MemoryBarrier
however is only supported for Windows 2000 which I see at
http://www.gtk.org/download/win32.php that is the minimum requirement
for the prebuilt distributions.  But MemoryBarrier doesn't need to be
used for XP since it isn't supported.  Hopefully any use of
MemoryBarrier is controlled by proper #if WINVER >= 0x0502 declarations.

Now on to other required GTK libraries.
