ac_aux_dir not set

[Stepan Kasal]

Hello,
  I encountered a problem with a configure script which used
ac_aux_dir before it was set.

I found out that the macro AM_AUX_DIR_EXPAND supposes that ac_aux_dir
is ready.  The natural way to express this assumption is:
        AC_REQUIRE([AC_CONFIG_AUX_DIR_DEFAULT])

This bug does not hit in the usual case when AM_INIT_AUTOMAKE is
called before any other AM_* macros, and the above AC_REQUIRE is
brought in by AC_PROG_INSTALL.

In my case, AM_PROG_CC_C_O was called before AM_INIT_AUTOMAKE.

I looked quickly to the Automake manual, and I haven't found the rule
that AM_INIT_AUTOMAKE should be the first AM_* macro; is it really
there?

In any case, I suppose the attached patch should not hurt.

Thanks,
        Stepan Kasal
