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.
