[Bug testsuite/32841] FAIL: gfortran.dg/edit_real_1.f90 on Darwin8

["jvdelisle at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #3 from jvdelisle at gcc dot gnu dot org  2007-07-20 21:01 -------
Additional note: isfinite may be getting redefined in libgfortran.h

/* The isfinite macro is only available with C99, but some non-C99
   systems still provide fpclassify, and there is a `finite' function
   in BSD.

   Also, isfinite is broken on Cygwin.

   When isfinite is not available, try to use one of the
   alternatives, or bail out.  */
