compilation of statist under cygwin

[sfronzek@gmx.net]

Hi Andreas and Bernhard,

thanks for your replies. With your suggestions, I managed to compile
statist; however, about 200 warnings were issued similar to
"plot.c:434: warning: passing arg 1 of `out_err' makes pointer from integer
without a cast"

And, even worse, the program now crashes each time I try to read in some
data.
