[net.unix-wizards] if statement ambiguity

stevens (09/23/82)

The trick I use is to define the macro like this:
	#define mymacro		if (e1) s1; else
-or-
	#define mymacro		if (e1) {s1;} else
Then both
	mymacro;
-and-
	if (whatever)
		mymacro;
	else
		stmt;
work like you would expect.
This also works for things like:
	#define TRACE(stmt)	if (tracing) {stmt;} else
so you can do
	TRACE(printf("Got to this point.\n"));
