System: FreeBSD cae88-102-101.sc.rr.com 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Wed Nov 15 00:22:26 EST 2000 root@cae88-102-101.sc.rr.com:/usr/src/sys/compile/RHIANNON i386

>Description:
	The header file <stdbool.h> contains a defective
conditional that breaks several ports.  Any code that includes
<stdbool.h> will break if compiled by gcc...  Example:

#include <stdbool.h>

int main()
{
	return(0);
}

$ cc test.c
In file included from test.c:1:
/usr/include/stdbool.h:51: conflicting types for `_Bool'
/usr/include/stdbool.h:38: previous declaration of `_Bool'

>How-To-Repeat:
	See above :)
