Wouldn't it make sense to add a self-test for this, which would fail on
all other platforms, but on Solaris, return -77 to cause a SKIP?
Possibly also print a message with a link to this thread.  That way,
people building on Solaris will notice the issue and someone may
eventually get it fixed upstream.

If there are no objections, I'll write up a self-test.
