No, because I see the identical content in stdbool.h on OS X 10.4
(perl 5.8.6) and it is not causing a problem here. Apparently 5.8.8
is sucking stdbool.h into the compile where 5.8.6 did not. Can you
track down just what the inclusion path is?
I'm tempted to fix this with
#ifdef bool
#undef bool
#endif
in plperl.h after pulling in the Perl headers. However, it's not clear
to me why you aren't seeing warnings about "false" and "true" getting
redefined, if stdbool.h is really getting included.
For reference, the interesting part of stdbool.h on 10.4 looks like
#define false 0
#define true 1
#define bool _Bool
#if __STDC_VERSION__ < 199901L && __GNUC__ < 3
typedef int _Bool;
#endif
Since this is gcc 3, I suppose that the typedef isn't being used here
but must get supplied internally by the compiler...
