[Scons-users] custom builder for use with wine

[Dirk Bächle]

Patrick,

thanks a lot for your example. Hacking around a little, I found a 
solution that works (see attached file)...but doesn't look very pretty.
The problem is that all custom defined tests get called as a 
CheckContext, which sort of wraps the actual SConfBase class.

This is the reason why simply adding "TryWine" to "SConfBase" is not 
enough, you have to provide the delegate method for "CheckContext" too.

Regards,

Dirk
