What do I have to hack in XPaint 2.1 package to set it up OK for NetBSD 1.1
   and XFree86 3.1.2?

I have xpaint v2.1.1 running with a 1.1 system.  I compiled/installed
it as follows:

     patch < ../xpaint-2.1.1.patch
     xmkmf -a
     make && make install && make install.man

The patch is attached below.  Note that there is a new version (2.2, I
think) out.

Hope this helps.

Cheers,
Brook
