Currently building on Sequent PTX 4.4.10.
Yes, this is a rare OS.
use of uint8_t and uint32_t is new since 3.0.14.
configure ought to look for it and set up defines as necessary.
(cleaning up old bugs)
The WAF build system introduced with Samba 4.0 checks all these types.
(I'm not sure it would build on Sequent however)
