Fixed bug 1587 - "aclocal" fails to generate a sufficient "aclocal.m4" Cecil Curry 2012-08-27 16:55:12 PDT Allow "aclocal" to find the "AC_CHECK_DEFINE" macro. On running: rm aclocal.m4 libtoolize --install --copy --force aclocal -I acinclude autoconf -I acinclude The former three commands succeed, but "autoconf" fails with: configure.in:198: error: possibly undefined macro: AC_CHECK_DEFINE If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. "aclocal" fails to find AC_CHECK_DEFINE and hence add such macro to "aclocal.m4". Here is why: * "acinclude/ac_check_define.m4" defines AC_CHECK_DEFINE via define() rather than AC_DEFUN(). * "aclocal" fails to find macros defined via define().
