  Log:
  Implement the classification macros isfinite(), isinf(), isnan(), and
  isnormal() the hard way, rather than relying on fpclassify().  This is
  a lose in the sense that we need a total of 12 functions, but it is
  necessary for binary compatibility because we have never bumped libm's
  major version number.  In particular, isinf(), isnan(), and isnanf()
  were BSD libc functions before they were C99 macros, so we can't
  reimplement them in terms of fpclassify() without adding a dependency
  on libc.so.5.  I have tried to arrange things so that programs that
  could be compiled in FreeBSD 4.X will generate the same external
  references when compiled in 5.X.  At the same time, the new macros
  should remain C99-compliant.
  
  The isinf() and isnan() functions remain in libc for historical
  reasons; however, I have moved the functions that implement the macros
  isfinite() and isnormal() to libm where they belong.  Moreover,
  half a dozen MD versions of isinf() and isnan() have been replaced
  with MI versions that work equally well.
