Wez, could you please explain what is the function of #define 
_XOPEN_SOURCE in ext/standard/proc_open.c? It breaks build (by preventing 
ulong and other types from being define) on some systems, like Solaris or 
NetBSD. Is it necessary?

I thought I had replied-to-all, but obviously not.

If you don't define _XOPEN_SOURCE under linux, you see the very same breakage
that you see under Solaris if you define it.  Another fine mess...

Magnus and myself have been and will be continuing our investigation of this
stuff today.
