Getting at path to AC_CONFIG_AUX_DIR

[Rhys Ulerich]

'afternoon,

I'm putting together a (hopefully reusable) macro the requires a script in
my AC_CONFIG_AUX_DIR directory:

AC_DEFUN(AC_FOOBARBAZ,[
#...
AC_REQUIRE([AC_CONFIG_AUX_DIR_DEFAULT])
AC_REQUIRE_AUX_FILE([tex-it])
AC_SUBST(ac_aux_dir)
# Output a script that will later invoke $(ac_aux_dir)/tex-it during Make
#...
])

This is a little klunky.  Is there a better way to get of the configured
AC_CONFIG_AUX_DIR than hijacking ac_aux_dir with AC_SUBST?

Thanks,
Rhys
