grafX2/const.h
Adrien Destugues 9933e1fddc We can now build on tru64. Mountlist.c doesn't seem to work so it crashes when trying to do something in the loadsave screen. 
As the available machines don't have gdb, I can't go much further...
I could try building with compaq compiler but it seems a lot more strict than gcc. Do you want me to fix these problems to get cleaner ansi code (may be less readable...)
