Nasty. I'm still surprised that there's no redefinition warning for
"false" and "true", but that's not too important, since the cast to
(bool) isn't really critical. I guess what we need is as attached;
would you try it and see?

How far back should we patch this? Is anyone likely to care about
pre-8.2 plperl on Leopard?

Another thought here is that c.h tries to cater to the possibility
of bool being #define'd by system headers, but if that did actually
happen anywhere then this patch would fail. We'd have pretty serious
problems anyway if bool were not char-size, since pg_type.h hardwires
its size as 1 byte. So I'm a bit tempted to remove the "#ifndef bool"
from c.h, or else make it do "#undef bool". Comments?
