Hi Will,
sorry, I have almost never used mwin (always nanoX) so
I can't tell you much about that, however the file
header of conv_bmp.c says:
* 9/24/2003 endian-neutral conversion
so I guess that there should be some support (maybe
buggy for big endian too) ...
would you mind share with us your mods. If it comes
that conv_bmp.c do have problems in big endians, we
should correct that in the current tree.
