No, its a requirement of the C programming language.

If you don't put the types on the parameter list to your function, it will
assume type "int"... this goes back to K&R C, and was part of the C standard.

could also be written as
typedef struct MyIrEvent {
IrEvent IrEvt;
UInt16 test;
} MyIrEvent;
to avoid having a struct tag name that's gratuitously different from the
typedef name.

Write this as
static void DoIR( /* some type I don't know */ MyIRC, MyIrEvent *MyIrEvt) {
switch(MyIrEvt->IrEvt) { // this won't compile
case LEVENT_DATA_IND:
break;
// more case stuff below
}
I don't understand what you're trying to do declaring the parameters
without types.
