  expm1l: Work around inaccurate implementation on NetBSD.
  
  * lib/math.in.h (expm1l): Test also REPLACE_EXPM1L.
  * m4/expm1l.m4 (gl_FUNC_EXPM1L): Add test for a certain accuracy. Set
  REPLACE_EXPM1L.
  * m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_EXPM1L.
  * modules/math (Makefile.in): Substitute REPLACE_EXPM1L.
  * modules/expm1l (Depends-on, configure.ac): Test REPLACE_EXPM1L.
  * doc/posix-functions/expm1l.texi: Mention the NetBSD bug.
