acinclude.m4 ([GLIBCXX_CHECK_GETTIMEOFDAY]): Change to use GCC_TRY_COMPILE_OR_LINK.
2008-08-23 Paolo Carlini <paolo.carlini@oracle.com> * acinclude.m4 ([GLIBCXX_CHECK_GETTIMEOFDAY]): Change to use GCC_TRY_COMPILE_OR_LINK. ([GLIBCXX_CHECK_CLOCK_GETTIME]): Rename to [GLIBCXX_ENABLE_CLOCK_GETTIME], a versatile configure-time option, [no] by default, since it includes TRY_LINK checks. librt is also searched, if requested. * doc/xml/manual/configure.xml: Document the latter. * configure.ac: Move the above checks outside native-only. * configure: Regenerate.
