Subject: Re: [OMPI devel] 1.7.4rc1 build failure: OpenBSD-5 and NetBSD-6

Jeff,

The unofficial "rc2forpaul" gets past the (disgusting) if_mtu problem on
both platforms.

On NetBSD-6 the build completes ("make install" fails, but I'll report that
separately).

However, on OpenBSD-5 we now encounter another failure about 20 files later:

  CC sys_limits.lo
/home/phargrov/OMPI/openmpi-1.7.4rc2forpaul-openbsd5-amd64/openmpi-1.7.4rc2forpaul/opal/util/sys_limits.c:

*** Error 1 in opal/util (Makefile:1692 'sys_limits.lo': @echo " CC "
sys_limits.lo;depbase=`echo sys_limits.lo | sed 's|[^/]*$|.deps/...)
*** Error 1 in opal/util (Makefile:1780 'all-recursive')

The getrlimit manpage on this platform does not list RLIMIT_AS.
Running "grep -rl RLIMIT_AS /usr/include" confirms that this constant does
not exist.
So, I think "#ifdef RLIMIT_AS" is required.
