  round: Don't override undeclared system function on IRIX 6.5.
  
  * m4/check-math-lib.m4 (gl_CHECK_MATH_LIB): Accept an optional third
  argument.
  * m4/round.m4 (gl_FUNC_ROUND): Search for round() in the libraries
  also when it is not declared. Set HAVE_ROUND. For replacement code,
  test HAVE_ROUND, not HAVE_DECL_ROUND.
  * modules/round (configure.ac): For replacement code, test HAVE_ROUND,
  not HAVE_DECL_ROUND.
  (Depends-on): Update conditions.
  * modules/round-ieee (Depends-on): Update conditions.
  * doc/posix-functions/round.texi: Mention the IRIX problem.
