 		 #166405 - SDCC Quirk?
Responding to: Jan Waclawek's previous message
Jan Waclawek said:
.... the main() function would be the "bearer" of the interrupt vector, which in turn does *call* the ISRs.

Yes, I dare say it's something like that.

Maybe someone who knows the internals of SDCC will be along soon to explain it to us...

Although this is a quirk of SDCC, I don't think it's a completely unreasonable one. Certainly including *prototypes* of ISRs shouldn't hurt in other dialects of C, either.

I'd have thought not, but...

However, the general principle of modular programming is to avoid publishing anything more widely than necessary.
Many Keil people make it their practice to declare ISRs as static - so that a prototype really is meaningless!
