Summary: Yes

Yes, I have seen this problem.  The compiler cannot cope with two functions
returning float/double in the relational expression.  It seems to handle other
kinds of floating point operands better, so when I need a work-around I rewrite

	if (f(x) < g(y)) ...

as

	{ double t = f(x);
	  if (t < g(y)) ... }

Being sure, of course, to make the result more readble than this.  There's a
belief locally that this is fixed in V.3.1 (and later?) cc for the 386.
