I have created an m4 directory in my source tree, and put some macros
downloaded from the autoconf macro archive in there. I also added
AC_CONFIG_MACRO_DIR([m4])
to configure.ac, and this causes autoreconf to (correctly) put
libtool.m4 and ltdl.m4 into the m4 directory.
However, aclocal does not pick up the contents of this directory into
aclocal.m4 unless I add
ACLOCAL_FLAGS=-I m4
to Makefile.am. Is this the proper way to get aclocal to pick up these
macros?
