  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.
