Wishlish: GCC option for explicit booleans

[Peter Lupton NCH Swift Sound]

Richard: based on your argument all type checking is for nought :).

But I have been going through other reports from the 'bug book' which I ask 
my programmers to log. Another case which explicit bools would solve would 
be (in Win32)...

         HANDLE hFile = CreateFile(...);
           if (!hFile) return;

If the compiler had forced the writer to make a real comparison, I am sure 
the bug would never have made it into release.  The problem here is 
INVALID_HANDLE_VALUE is -1 not 0.
