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().
