It would be nice to take OpenBSD 3.9 as the OpenBSD version for 
the next release; C99 headers are a much saner environment.

If we really want to support older versions, we can probably work around 
the headers with cpp #ifdef hackery (it would be especially nice if 
someone knows of a #define constant corresponding to the OpenBSD version), 
but I don't know how best to handle the signedness change in 
basis-library/config/c/x86-openbsd/c-types.sml.  Its probably o.k. to lie 
about the signedness (since signd and unsigned 32-bit integers are handled 
the same by the C calling convention).
