[Mono-dev] Using an alternate System.Windows.Forms

You can override the GAC used by Mono by setting the MONO_GAC_PREFIX
environment variable.   You can set this from C before you init Mono,
and would let you say "Use this GAC before you try the System GAC"

char dir = g_string_concat (bundle_dir, "Contents/MyMonoPrefix", NULL);
setenv ("MONO_GAC_PREFIX", dir);

Then recreate the basic directory structure under Contents/MyMonoPrefix:

lib/mono/gac/System.Windows.Forms/XXXXX/System.Windows.Forms.dll
