  fmod-ieee: Work around test failures on OSF/1, mingw.
  
  * m4/fmod-ieee.m4: New file.
  * m4/fmod.m4 (gl_FUNC_FMOD): If gl_FUNC_FMOD_IEEE is present, test
  whether fmod works with zero arguments. Replace it if not.
  * lib/math.in.h (fmod): New declaration.
  * lib/fmod.c: New file.
  * m4/math_h.m4 (gl_MATH_H): Test whether fmod is declared.
  (gl_MATH_H_DEFAULTS): Initialize GNULIB_FMOD, REPLACE_FMOD.
  * modules/math (Makefile.am): Substitute GNULIB_FMOD, REPLACE_FMOD.
  * modules/fmod (Files): Add lib/fmod.c.
  (Depends-on): Add math, isinf, trunc, fma.
  (configure.ac): Arrange to compile lib/fmod.c if needed.
  * modules/fmod-ieee (Files): Add m4/fmod-ieee.m4, m4/minus-zero.m4,
  m4/signbit.m4.
  (configure.ac): Invoke gl_FUNC_FMOD_IEEE.
  * tests/test-math-c++.cc: Check the declaration of fmod.
  * doc/posix-functions/fmod.texi: Mention the fmod-ieee module.
