Our old Autotools Build System (ABS, which you are currently using) does not
allow this.  However, we also have a new much more flexible CMake Build
System (CBS) that has been essentially completed for Linux (and which is
still being worked on to implement complete builds of PLplot on Mac OS X and
windows).  Currently our CBS just follows our old ABS and disallow wxwidgets
for the static case.

However, I just came up with an idea about a change to our CBS that should
make a static wxwidgets device work without mixing C and C++ code in the
same library.  The gist is when dynamic devices (plug-ins) are disabled,
then two additional separate libraries (one for C driver code and one for
C++ driver code) are made and our core library is linked to those two
additional libraries.  I generally like this idea because it means device
driver code never gets into our core C library under any circumstances.
Also, that linking should automatically be the desired static linking if you
generally disable shared libraries for the PLplot build.

The change means some CMake configuration reorganization so it may take a
while (a day or so) to implement and test it. Joe, once I have done that, I
will get back to you with the details so you can try this proposed CBS-based
static linking for the wxwidgets device for yourself.
