> gtags-cscope: re-implemented using cscope's code

Gee, you make life hard for me. ;)  The patch is here:

        http://adoxa.110mb.com/global/glo595.txt

Due to CMD's limitations, the system calls use double quotes instead
of single quotes; hope that doesn't cause problems.  I also removed
CURSES_LIB from the dependencies (the make from UnxUtils didn't like
it, didn't think to try with mingw32-make; djgpp was fine, though, so
perhaps you could leave it and I'll have another look next release).
