Yeah. I am converting it to use TCHAR everywhere except for the file
header checking. Seems the easiest way.

Indeed.

My current problem is that EPSExportDC is derived from CCDC which
in turn is derived from wxDC. This has so many pure virtuals
(many tens of them) that I can't see how this is ever meant to
work. In the windows build it seems to be derived from CDC,
which I am guessing is somehow not full of pure virtuals.

How are you handling this with your filter code?
