For example, when compiling screen on my ultra60, it whined because the auto* tools in their infinite wisdom (or lack thereof) define ioctl as so in osdef.h: extern int ioctl __P((int, int, char *)); In sys/sys/ioccom.h we have: int (ioctl)(int, unsigned long, ...); Note that the second arg is a long rather than an int, plus the 3rd argument isn't defined. Obviously then, the protoypes aren't going to match up on platforms where sizeof(long) != sizeof(int). Actually, I just tried taking out the parens around ioctl and now screen still doesn't build on my i386 laptop running today's current: > make ===> Building for screen-3.9.11_1 cc -c -I. -I. -O -pipe screen.c In file included from screen.h:38, from screen.c:85: osdef.h:87: conflicting types for `ioctl' /usr/include/sys/ioccom.h:75: previous declaration of `ioctl' I have to wonder why screen(1) has decided that it has a better prototype for ioctl() than the base system headers. That seems to be the real bug to me. :( -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
