Re: [AD] dll binary compatibility maintenance.

[Henrik Stokseth <hstokset@xxxxxxxxxx>]

just committed the following patch.

please remember to add functions and variables you remove from allegro to 
include/allegro/compat.h and src/win/compat.c. (but only symbols that are 
exported)

ps! i'm going to commit the dll version resource script soon along with the 
needed makefile updates. it's kinda cool to view additional info on the 
allegro DLL when you right-click on the dll and select 'properties' ;o)
