Re: Wishlish: GCC option for explicit booleans
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.

If you're that lazy programmer you're going to stick (bool) in front of it
to silence the warning.
Duh.
