Hi Walt:

I am fairly sure the unofficial versions of GTK+ at www.tarnyko.net/dl
are the same as the official versions accessible at
http://www.gtk.org/download/win64.php and
http://www.gtk.org/download/win32.php, but in any case you should be
using only the latter, the official 32-bit version rather than a
64-bit version (official or unofficial) or an unofficial 32-bit
version from www.tarnyko.net/dl. (See the remarks at
http://www.gtk.org/download/win64.php concerning the experimental
nature of the 64-bit version and its known incompatibility with MinGW.
And, for now do not use mingw-64 (an additional platform beyond Cygwin
and MinGW which is substantially different than MinGW) since we have
zero experience with mingw-64.)

Also, the cmake command you reported, i.e.,

C:\"Program Files (x86)"\"CMake 2.8"\bin\cmake -G "MinGW Makefiles"
-DDEFAULT_NO_BINDINGS=ON -DENABLE_f95=ON
-DENABLE_DYNDRIVERS=ON -DCMAKE
INSTALL_PREFIX=install .. 1>cmake.out 2>cmake.err

is not quite right.  That option should instead be

-DCMAKE_INSTALL_PREFIX=install

Furthermore, you must use the svn trunk version of PLplot which
contains our latest build-system changes for the GTK+ version 3 case.
The PLplot build system for that version of GTK+ is still a bit rough
so instead of figuring things out for itself you have to explicitly
use the

-DDROP_GTK_PLUS_2_BUILDS=ON

cmake option to drop minor parts of the PLplot build that are not
compatible with GTK+ version 3.

I am now going to try the official all-in-on bundle of GTK+ accessible
at http://www.gtk.org/download/win32.php under Wine with the PLplot
svn trunk version and with -DDROP_GTK_PLUS_2_BUILDS=ON to see how far
I get. But please try that yourself at the same time rather than
waiting for me since Wine has severe startup latency for every command
that (assuming it works) is going to significantly delay when I can
get back to you with the result to compare to yours (which might work
right out of the box).  This Wine startup latency doesn't matter a bit
for long tasks such as running a game, but for build and test tasks
that might easily require 0.1 million short commands to run, the
startup latency of typically 0.3-0.5 seconds for each of those
commands takes a huge toll (roughly 10-15 hours) for a build and test
task that should take only 0.5 hours on Microsoft Windows.
