aclocal: fix for more-than-once specified directories Related to automake bug#13514. Do not consider directories for extra m4 files multiple times in 'aclocal'. Doing so caused problems on older packages that specify configure.ac: AC_CONFIG_MACRO_DIRS([m4]) Makefile.am: ACLOCAL_AMFLAGS = -I m4 if the 'm4' directory does not exist when aclocal is called the first time by autoreconf. See: <http://lists.gnu.org/archive/html/bug-automake/2013-01/msg00115.html> * aclocal.in (scan_m4_files): Remove duplicates in @user_includes. * t/aclocal-macrodir.tap: Extend. * t/aclocal-macrodirs.tap: Likewise.
