Hi Walt:

Six hours later (because the builds of PLplot dependencies on Wine are
really slow for the reasons I mentioned and one false start that
wasted a couple of hours) I finally got to the point of building
PLplot using the "MinGW Makefiles" generator against epa_built
versions of all its dependencies other than the GTK+ stack and the
official 32-bit binary version of GTK+ for Windows which is supposed
to be compatible with MinGW.

The result verified the PLplot "MinGW Makefiles" build-system issue that Walt found
previously on Microsoft Windows (which also verifies once again that
Wine is a fairly reliable but slow! Windows test platform); for some
strange reason parts of the GTK+ stack are being found by pkg-config but
other parts are not being found so the overall effect is the cairo
devices are all being dropped.  This pkg-config result works fine on
Linux so the whole thing is quite a puzzle.

I will look further at this tomorrow (Wednesday) now I have confirmed
this Windows platform PLplot build-system (or perhaps pkg-config)
issue for the PLplot pango/cairo stack dependencies.
