Quite a few months ago, I made an attempt to get screen 4.0.2 running on cygwin. I was far from fully successful and my need to run screen on cygwin since then has waned. But since I haven't seen any cygwin patches for 4.0.2 out there, I figured I would share what I had in case anyone else would find it useful.
The attached patch applies to the stock screen 4.0.2 distribution. The resulting binary will require a fairly recent cygwin dll (post early 2005) -- one of the things I found was that screen would not reattach because cygwin at the time did not implement chmod on fifos, but that was pretty promptly fixed after I brought it up on the cygwin mailing list. The basic functionality that works now is detaching and reattaching with 'screen -r'. 'screen -x' does not work, and I'm sure a number of other things also don't work. A curious thing about reattaching is the following: I use rxvt, and if I start up screen and then detach, then reattaching will not work. First I need to close that rxvt terminal and then open a new one; running 'screen -r' now works. So in summary, reattaching seems not to work in the original terminal that I started the screen in. Another funny thing is that in the seven or so months since I last did any work on this, cygwin appears to have become broken somehow, in that screen's configure script no longer runs properly. A 'conftest' executable generated during the configure process appears not to exit properly, and this causes attempts to delete conftest to fail. For that reason, if there is any interest, I'd be willing to post my compiled screen.exe somewhere. A final note is that I only run cygwin on Windows XP. I've gathered from other patches out there that there may be some issues with cygwin on older versions (e.g., Windows 98), but I have no idea if that applies here.
