Yeah. c.h has
#ifndef __cplusplus
#ifndef bool
typedef char bool;
#endif /* ndef bool */
#endif /* not C++ */
#ifndef true
#define true ((bool) 1)
#endif
#ifndef false
#define false ((bool) 0)
#endif
It's been like that for quite some time, but it's always struck me as
bizarre: if we're willing to trust a C++ compiler to provide type
bool, why would we not trust it to provide the literals true and false
as well? ISTM the code should read
#ifndef __cplusplus
#ifndef bool
typedef char bool;
#endif
#ifndef true
#define true ((bool) 1)
#endif
#ifndef false
#define false ((bool) 0)
#endif
#endif /* not C++ */
Does anyone have an objection to this?
