C++ header file problem - is this a bug?

[Bill Northcott]

Sorry I don't get that.  Where is the bug in the following code?
#include <iostream>
#include <math.h>
isnan(x);

isnan() is a macro defined in math.h, but it does not work in this 
snippet.  How do you suggest this code is 'fixed'??

As discussed in PR14608 the bug is in gcc.  Various macros in math.h 
don't work if cmath.h also gets included.  It comes up with all sorts 
of code on different platforms.
