Description: Include missing m4 macro
 Running autoreconf fails because the AC_FUNC_SNPRINTF macro isn't part
 of autoconf upstream, but rather was pulled in from an external resource
 (e.g., http://ac-archive.sourceforge.net/ac-archive/ac_func_snprintf.html).
 Include it in the tree so that autoreconf works correctly.
