Compiler warnings from strict ISO C90 checking

[Ethan M. <merritt@u.washington.edu>]

For what it's worth, compiling with "gcc -pendantic" produces the warnings below.
I don't know if this is a problem for any real set of c/c++ compilers used to
build gnuplot with wxt support.

Thanks for the report. I fixed the warnings in CVS.

By the way, I tried to do the same for wxt_gui.cpp, by compiling with=20
CXX=3D'g++ -pedantic' but it fails because wxWidgets headers use the type=
=20
"long long". I don't know what to do to check my code without failing on=20
wxWidgets headers.

Best regards,

Ok, I figured out that the type "long long" has been introduced in the=20
standard C99, and compiling with CXX=3D'g++ -pedantic -Wno-long-long' is=20
enough to make wxt_gui.cpp compile, without  any warning.
