acinclude.m4 ([GLIBCXX_CHECK_LFS], [...]): Use GCC_TRY_COMPILE_OR_LINK instead of AC_TRY_LINK... 

2008-08-17  Paolo Carlini  <paolo.carlini@oracle.com>

	* acinclude.m4 ([GLIBCXX_CHECK_LFS], [GLIBCXX_CHECK_POLL],
	[GLIBCXX_CHECK_S_ISREG_OR_S_IFREG], [GLIBCXX_CHECK_WRITEV]):
	Use GCC_TRY_COMPILE_OR_LINK instead of AC_TRY_LINK, in C++,
	with -fno-exceptions as flags.
	* configure.ac: Run unconditionally GLIBCXX_CHECK_LFS,
	GLIBCXX_CHECK_POLL, GLIBCXX_CHECK_S_ISREG_OR_S_IFREG,
	GLIBCXX_CHECK_WRITEV and commonized AC_CHECK_HEADERS. 
	* crossconfig.m4: Adjust; remove AC_CHECK_HEADERS commonized
	in configure.ac.
	* configure: Regenerate.
