"FreeBSD fix"

[Eddie Kohler]

Yo Robert!

What's up with your "FreeBSD fix" adding an IPAddress(unsigned long)
constructor?

If u_int32_t is typedef'ed to "unsigned long" (which would be perfectly
legal), your fix will cause compilation problems.

We should "fix" FreeBSD in some other way, probably by casting to
u_int32_t. I'll change back ipaddress.hh at some point ... but will wait to
hear from you.

p.s. I saw your closed door!
