well, i saw a bunch of your commits and comments to win32.c in the
archives, i was hoping you were that dev.

there is  "DecodePointer" and "EncodePointer" , i was just unsure
how to add the alternative spelling of _encode_pointer _decode_pointer.

right. but i left atl90 struct there so i could add the numerical
exports if i figured that out.

i agree, you came up with a half-patch to do it long ago:
http://mplayerhq.hu/pipermail/mplayer-cvslog/2009-September/037502.html

you think we could just put all of the emulated functions under one
struct and that one struct could be all.dll ? it would simplify
things.
