For example it is the path for the --install option. Also, the first include is treated in a special way if it doesn't exists. This might be the case if there is the following construct: configure.ac: AC_CONFIG_MACRO_DIR([m4]) Makefile.am: ACLOCAL_AMFLAGS="-I m4" If the package doesn't have local macros, the m4/ directory might not exist. aclocal will then just issue a warning instead of aborting the execution with a fatal error. See discussion here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=565663 Don't use the "-I" option in aclocal. Instead use ACLOCAL_PATH to pass the system-wide include dirs. As a side effect this should fix the use of $(ACLOCAL) alone. Up until now, $(ACLOCAL) didn't include the ACLOCAL_HOST_DIR system include path. autoreconf will pass the "-I" options to every tool it runs, of which aclocal, which, as seen above, we don't want. So move the argument down to each individual tool, except for aclocal.
