  Add autoconf test to detect x87-style double rounding, as described in
  issue #2937.  This information can be helpful for diagnosing platform-
  specific problems in math and cmath.  The result of the test also
  serves as a fairly reliable indicator of whether the x87 floating-point
  instructions (as opposed to SSE2) are in use on Intel x86/x86_64 systems.

  isinf and isnan are macros, not functions; fix configure script
  to use AC_CHECK_DECLS instead of AC_CHECK_FUNCS for these.
  (See discussion in issue #4506)
