autoreconf not passing -I option to aclocal

[Guillaume Rousse]

I got troubles using autoreconf with custom macros. It appears than
autoreconf doesn't pass -I option to aclocal for importing them, only to
autoconf, but it does not seems to be enough:

address@hidden camlimages]$ autoreconf -v -I ../autoconf/
autoreconf-2.5x: Entering directory `.'
autoreconf-2.5x: configure.ac: not using Gettext
autoreconf-2.5x: running: aclocal
autoreconf-2.5x: configure.ac: tracing
autoreconf-2.5x: configure.ac: not using Libtool
autoreconf-2.5x: running: /usr/bin/autoconf --include=../autoconf/
configure.ac:8: error: possibly undefined macro: AC_PROG_OCAML
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf-2.5x: /usr/bin/autoconf failed with exit status: 1

AC_PROG_OCAML is defined in ../autoconf/ocaml.m4 file.
