can't build without gcc. Libvirt fell into this group, and are curious if anyone has any ideas on why this breakage would occur.
Here is a link to the buildlog:

The relevant section:

What does RAND_MAX expand to?

stdlib.h:#define RAND_MAX 0x7fffffff

And on our current head release (10) it is this: #define RAND_MAX 0x7ffffffd Sorry for the double-mail. -jgh -- Jason Helfman | FreeBSD Committer jgh@FreeBSD.org | http://people.freebsd.org/~jgh | The Power to Serve
