Doh!  I forgot about that fix in xpm.h.  It *used* to always include
some random X11 header file, and *that* header file was included in the
xpm dist and clashed with tk/tcl.  NOW, if XPM_NO_X || FOR_MSW, xpm.h
only includes "simx.h"; xpm.h includes X11 headers if the previous flags
are NOT defined.  So, the extraneous X11 files are not included in the
xpm dist.

Implication:  you can't build X-based xpm apps unless you also have the
x11 headers / libs installed in /usr/X11R6/*.  Fair enough -- and there
is no conflict with tk/tcl.

Thanks for the correction.

probably. :-)
