Calls to AddFontResourceEx seems to fails in various games.

San Andreas Multiplayer:
warn:font:new_ft_face Unable to load font
"/home/samuel/.wine/dosdevices/c:/Program Files/Rockstar Games/GTA San
Andreas/gtaweap3.ttf"/(nil) err = 2

Multi Theft Auto:
warn:font:new_ft_face Unable to load font
"/home/samuel/.wine/dosdevices/c:/Program Files/MTA San Andreas
1.4/MTA/cgui/pricedown.ttf"/(nil) err = 2

In both cases the fonts exist and seems to be valid.

What is error 2?
