FFI: Allow 'typedef _Bool int BOOL;' to make Windows users happy.
'_Bool unsigned int' works too. But no other combinations.
And, yes, this will affect the return types, too. So you need to
replace all of those:
if ffi.C.IsZoomed(w) ~= 0 then ... end
with:
if ffi.C.IsZoomed(w) then ... end
It's up to the user to declare BOOL, so this change doesn't break
existing code. But we'll definitely need to get some agreement for
the common Windows FFI declarations.
