Re: io on openbsd - problems installing

> I finally got back to this... Below is the diff that got it working on OpenBSD on the latest build.  I haven't attacked the addons yet, and but "gmake test" does appear to give the same output on OpenBSD as on my mac.

> Salient changes:
> 1) Add "OpenBSD" to the Makefile and the tools Makefile where FreeBSD is
> 2) Change the line for the tests from "make test" to "($MAKE) test" (it should be this anyway I believe.
> 3) Add "OpenBSD" to PortableStdint.h where FreeBSD is
> 4) Hack #1 - force USE_SETJMP in the coroutine/Makefile.  This should be done with proper platform pragmas but there ya go.
> 5) Hack #2 - hardwire the number of CPUs to 1 in IoSystem.c.  This should also be done with proper pragmas
> 6) Add a Coro_setup routine for OpenBSD in Coro.c. I copied the one from DragonFly BSD, but it looks obsolete - there needs (beyond the correct offsets) to be the right elements set up in globalCallbackBlock.
