ExceptionalCondition() return type

I came across this comment:

/*
* ExceptionalCondition - Handles the failure of an Assert()
*
* Note: this can't actually return, but we declare it as returning int
* because the TrapMacro() macro might get wonky otherwise.
*/

But it seems to me that this can easily be fixed like shown below, which
compiles without warnings. Is there any problem with that?

I noticed that the comment at TrapMacro suggests this usage pattern

#define foo(x) (AssertMacro(x != 0) && bar(x))

but all actual uses of AssertMacro() chain it using the comma operator.
Maybe that had something to do with it in the past, but it doesn't seem
likely either.
