GP 2.0.17 was compiled natively for Windows (thanks to Bill Daly) using
MSVC compiler. To my knowledge, the readline library doesn't exist for
Windows in this setting. It should be possible to create a readline.dll
usable by MSVC, using cygwin.dll, but it would take some work [and access
to MSVC, which I don't have].

GP 2.0.12 had been cross-compiled from a Linux box, using a compatibility
package (EMX/RSX) and ran using ported Unix libraries, in particular
readline.

If you have Cygwin installed (developper tools needed), you can compile GP 
yourself for Windows exactly as on a Unix system. Binary is 50% slower
than on the same machine running Linux, though :-(

I'll try to compile a recent version running EMX + readline and upload it.

P.S: Does anybody use Cygwin without the full developper kit ? I could
upload a Cygwin binary as well.
