The changes here to remove the L prefix suggest that you're incorrect
compiling this in non-unicode mode - your build system (whatever it is
you're using) should be defining UNICODE or _UNICODE or something to
make this work correctly.

The change to how the extern "C" bits are done looks harmless. Can you
file a bug in bugzilla to make sure this doesn't get forgotten?

I'm not precisely sure what you mean - can you show the code you're
using to do this? Probably filing a bug on this with more detail would
be a good idea, I can try to fix it up (but probably won't get to it
for a couple of weeks, since I'll be on holiday with no access to a
windows development system).

I certainly have no plans to implement any colourkeying stuff, but I'd
review and commit a patch if one was provided.
