gnuplot caca terminal work on Cygwin-x86 but not Cygwin-x86_64

Thu May 1 10:51:00 GMT 2014

I have re-configured:

cd "E:\usr\Tatsu\cyg64work\gnuplotcvs\build"
CFLAGS='-g -O0' \
CXXFLAGS='-g -O0' \
../gnuplot/configure --prefix=/usr/local/gnuplotcvs --with-caca

and execute make and make install.

$ gdb /usr/local/gnuplotcvs/bin/gnuplot
