    Message : 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.
