Yeah, my bad.

I believe the issue is more profane: Mono is trying to launch
gmcs with bin/gmcs.bat, but the latter contains absolute paths
set by the Mono installer => the script is not relocatable.

Change gmcs.bat to look like this:

@"%~dp0\mono.exe" %MONO_OPTIONS% "%~dp0\..\lib\mono\2.0\gmcs.exe" %*

%~dp0 (a cmd.exe variable) is expanded to the actual path of
gmcs.bat, making the script relocatable.
