remainder-ieee: Work around test failure on OSF/1. * m4/remainder-ieee.m4: New file. * m4/remainder.m4 (gl_FUNC_REMAINDER): If gl_FUNC_REMAINDER_IEEE is present, test whether remainder works with a zero second argument. Replace it if not. * lib/math.in.h (remainder): Override if REPLACE_REMAINDER is 1. * m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_REMAINDER. * modules/math (Makefile.am): Substitute REPLACE_REMAINDER. * modules/remainder (configure.ac): Consider REPLACE_REMAINDER. (Depends-on): Update dependencies. * modules/remainder-ieee (Files): Add m4/remainder-ieee.m4. (configure.ac): Invoke gl_FUNC_REMAINDER_IEEE. * doc/posix-functions/remainder.texi: Mention the remainder-ieee module.
