  log1pf-ieee: Work around test failure on OpenBSD 4.9 and AIX 7.1.
  
  * m4/log1pf-ieee.m4: New file.
  * m4/log1pf.m4 (gl_FUNC_LOG1PF): If gl_FUNC_LOG1PF_IEEE is present,
  test whether log1pf works with a minus zero argument. Replace it if
  not.
  * modules/log1pf-ieee (Files): Add m4/log1pf-ieee.m4, m4/minus-zero.m4,
  m4/signbit.m4.
  (configure.ac): Invoke gl_FUNC_LOG1PF_IEEE.
  * doc/posix-functions/log1pf.texi: Mention the log1pf-ieee module.
