You can ignore *some* warnings, but not all. If a function is declared as
__fastcall__, you cannot call it without a prototype or bad things will
happen. Other functions should be ok as long as you supply the correct number
of parameters. Which means, that there shouldn't be problems with cgetc() -
are you sure about that?

The best way to avoid the problems would be to change the naming conventions
for fastcall functions, so missing prototypes are detected at link stage. This
is somewhere on my todo list...
