Jacques,

we have some issues on the installer you downloaded and a new version=20
up there that fixes the problem.

This is how you can fix it on yours (quoting Gonzalo):
"
I only needed to set the PATH like:
C:\> set PATH=3Dc:\cygwin\home\myuser\go-mono\install\bin;%PATH%

And then my mcs.bat file is just (in install\bin):
@cd c:\cygwin\home\myuser\go-mono\install\bin
@set MONOARGS=3D
@:loop
@if x%1 =3D=3D x goto :done
@set MONOARGS=3D%MONOARGS% %1
@shift
@:done
@mono ..\lib\mono\1.0\mcs.exe %MONOARGS%
