How hard would it be to add the following to the directory where standard
headers are kept?
/* stdbool.h -- almost conforming implementation for pre-C99 environments */
#ifndef __bool_true_false_are_defined
#define __bool_true_false_are_defined 1
/* program is allowed to contain its own definitions, so ... */
#undef bool
#undef true
#undef false
#define bool int
#define true 1
#define false 0
#endif /* !defined(__bool_true_false_are_defined) */
This provides 99% of the Boolean functionality that is actually used by
C99-based applications without having to implement _Bool at all.
