But they're *not* equivalent. c.h has #define true ((bool) 1) whereas so far as I can see the <stdbool.h> definition is just #define true 1 And if you put those two definitions together you will get a warning. The lack of one with c.h + <stdbool.h> means somebody is cheating. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
