The test intrinsic_nearest.f90 from the fortran testsuite included with gcc
fails on sparc-sun-solaris2.9 will all optimization levels. I can reduce it to
the following code:

-------------------------------------------
program test_nearest
  real inf, max, x
  integer infi, maxi
  equivalence (inf,infi)
  equivalence (max,maxi)

! ??? This is pretty sketchy, but passes on most targets.
  infi = z'7f800000'
  maxi = z'7f7fffff'

  x = nearest (-inf, 1.0)
  print *, x, -max
  if (x .ne. -max) call abort()
end
-------------------------------------------

The comment (from the original test file) makes me feel that perhaps the nearest
intrinsic is fine but only the values for infi and maxi are proven wrong, but
I'm not really sure. And, if it's the case, some "more universal" values should
be fed in.
