FreeBSD seabug.megapath.biz 9.0-STABLE FreeBSD 9.0-STABLE #0: Mon Jan 9 10:53:27 PST 2012 root@seabug.megapath.biz:/usr/obj/usr/src/sys/FARK amd64
>Description:
getconf outputs -1 for ULLONG_MAX (and ULONG_MAX on amd64), which seems strange. Another implementation that I checked outputs 18446744073709551615 like it should.
>How-To-Repeat:
getconf ULLONG_MAX
>Fix:
Patch attached. It creates a couple of compiler warnings but fixes the problem, maybe there is a better way to do it.
Patch attached with submission follows:
