Subject: Add dnl after AC_PROVIDE,
X-Git-Tag: fsf-origin~610
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=db2ff00887ce8ab70768fcd16d3c008cca1b37eb;p=thirdparty%2Fautoconf.git

Add dnl after AC_PROVIDE,
	AC_REQUIRE, and AC_BEFORE calls.
	Use AC_CHECKING and AC_TEST_LINK instead of AC_COMPILE_CHECK.
