Hi, Chris.

I've seen something similar on Mac OS X.

When building MEDM 3.1.3, it failed for me with the following error:

----
/usr/bin/cc -c               -DUNIX  -Ddarwin   -ansi   -O3 -g   -Wall

make[2]: *** [medm.install] Error 2
make[1]: *** [medm.install] Error 2
make: *** [src.install] Error 2

Upon investigation, this appears to be because my X.h supports the X
Generic Event extension (XGE) <http://www.x.org/wiki/Development/
Documentation/XGE>.  If it's helpful, here's a commit against an
xorg/proto/x11proto Git tree showing the change to X.h:

  http://cgit.freedesktop.org/xorg/proto/x11proto/commit/
  ?id=44e458285bb2e7771963a9ab9b5f03d2fb48e611

With XGE, a new event opcode has been added, GenericEvent=35, and
LASTEvent became 36 instead of 35.  Attached is a patch against MEDM
3.1.3 that will make it work if LASTEvent is 35 or 36.

I sent this patch to Ken Evans and Janet Anderson on January 7, 2009,
but have not heard a response from either.  Are they still maintaining
MEDM or should I have sent it to someone else?
