Yes. If we were really serious about optimizing logical expressions,
we would probably want to use Karnaugh maps. However, I just don
Any chance of getting this in some time soon? The key.c part of it fixes
the broken tcc (and probably lcc) builds. All tests passed with tcc for
me, which is neat.

Would it gain us much implementing De Morgan's theorem in the peephole
optimiser?

Well if you look at it from the point of view that we are
developing the ANSI Parrot spec there is no collision.

If the function is intended to be inlined, why we need prototype for it.
The INLINE function should have immediate implementation, and not prototype.
I will use the following macro to handle this.
#if defined(__GNUC__) /* && __GNUC__ > nnn */
# define INLINE __inline__
#elif defined(_MSC_VER) /*

Actually, XP says tests/interface first and be prepared to change it
if the code tells you to.
But XP is specifical
