Look at this:

#include <stdio.h>

typedef char /*int*/ BOOL;
#define TRUE 1
#define FALSE 0

main() {
   BOOL flag=(BOOL)isupper('E');
   return 0;

It fails with BOOL as char, but works as int
Can someone explain this reasonably?
It works well with Borland
I have been using this typedef for years and it seems standard, robust,
good, pretty, simple, near-machine, fast, compact...
It seems gods of chaos are conquering the world of computing
