Hi all, apart from patching the objc-load.m part, I also patched some portions that do with launching processes. All of the attempts at mixing MinGW-style loading with Cygwin-based code seem very messy, and in the end I'm not absolutely sure it was necessary: Cygwin has some issues with fork() that their command /bin/rebaseall ended up fixing for me.
It seems that after compiling and installing GNUstep, running /bin/rebaseall on all .dlls installed by Cygwin plus all .dlls produced by GNUstep fixes the issues. The only issue that remained for me is that SystemPreferences cannot load any of its preference panes. Printed in the console is "No such file or directory". It's not a big deal for me, as for any testing of the backend I can use Calculator.app instead. Also, I could not test CoreBase and Opal because CoreBase depends on ICU - 15mb+, so I did not go downloading it over cellphone. I'll try doing a clean checkout of GNUstep and see what needs to be applied before committing anything, but generally it seems GS works rather nicely.
