Slackware 14.0, problem compiling with wxt terminal for gnuplot 4.6, while OK for 4.4.4

[Mikhail K. <mko...@gm...>]

Hi

i am trying add wxt terminal support for gnuplot 4.6 in Slackware 14, as 
gnuplot 4.6.0 package included does not support wxt and wxWidgets libs 
are not included either.

I compiled wxPython-2.8.12.1. Now i can successfully compile and run 
gnuplot 4.4.4 with wxt terminal.

but for gnuplot 4.6 (i tried both 4.6.0 and 4.6.1) compilation of wxt 
teminal is not enabled. probably a relevant part from "config.log" file 
goes below, and there are many errors like this

configure:YYYYY: -c++ -c -g -O2   -I/usr/include conftest.cpp >&5
./configure: line XXXXX: -c++: command not found

Am i doing anything wrong? GCC is 4.7.1.

thank you
Mikhail
