The test is failing due to an actual deficiency in gcc; you need
to disable the built-in versions of lrint and friends for it to
pass.  I considered working around that in the test (as in
test-conj.c) and tricking the compiler into using the library
versions, but that really just hides the problem.

Yes, some work is needed to deal with i386's special precision
issues.  As you know, it's often hard to get gcc to even produce
the right code on i386, and I didn't spend an inordinate amount of
effort trying to get tests for long doubles to pass on that
