#193 plplot test failed with SWIG 4

[Jitka Plesnikova]

SWIG is preparing new release 4.0.0. and I am testing rebuild of SWIG's dependencies with it. During the rebuild I found that plplot test failed (see error below). I asked upstream for help and there are described possible solution https://sourceforge.net/p/swig/mailman/message/36603481/

Regards, Jitka
