Dear Yaakov Selkowitz

WxWidget on Cygwin may be built by old compiler.
This caused ABI mismatch warining on gnuplot for Cygwin
in plotting on wxt terminal.

gnuplot> pl x
07:54:00: Warning: Mismatch between the program and library build versions detected.
The library used 3.0 (wchar_t,compiler with C++ ABI 1009,wx containers,compatible with 2.8),
and your program used 3.0 (wchar_t,compiler with C++ ABI 1011,wx containers,compatible with 2.8).


The warning can be avioded if I attach patch to gnyuplot source.

However, if wxwidget are re-built using the current compiler this patch to gnuplot source
can be avioided.

Please consider the update.
