hypotl-ieee: Work around test failure on OSF/1 and native Windows. * m4/hypotl-ieee.m4: New file. * m4/hypotl.m4 (gl_FUNC_HYPOTL): If gl_FUNC_HYPOTL_IEEE is present, test whether hypotl works with mixed NaN and Infinity arguments. Replace it if not. * lib/math.in.h (hypotl): Override if REPLACE_HYPOTL is 1. * m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_HYPOTL. * modules/math (Makefile.am): Substitute REPLACE_HYPOTL. * modules/hypotl (configure.ac): Consider REPLACE_HYPOTL. (Depends-on): Update conditions. * modules/hypotl-ieee (Files): Add m4/hypotl-ieee.m4. (Depends-on): Add hypot-ieee. (configure.ac): Invoke gl_FUNC_HYPOTL_IEEE. * doc/posix-functions/hypotl.texi: Mention the hypotl-ieee module.
