Must call AC_CONFIG_AUX_DIR before AM_INIT_AUTOMAKE

[Albert Strasheim]

Hello,

You might want to consider updating the info documentation of the 
AC_CONFIG_AUX_DIR macro to reflect the fact that it should be called 
before the AM_INIT_AUTOMAKE macro.

If this is not done, two sections of code to work out the value of the 
ac_aux_dir variable are added to the generated configure script.

For example, calling the macros as follows:

AM_INIT_AUTOMAKE
AC_CONFIG_AUX_DIR(config)

results this error message being printed when configure is run:

configure: error: cannot find install-sh or install.sh in . ./.. ./../..

Essentially, at the time the for loop in AC_CONFIG_AUX_DIRS is first 
executed, the list of directories it uses to figure out the value of 
ac_aux_dir does not yet contain the directory passed to
AC_CONFIG_AUX_DIR.

The info documentation of AM_INIT_AUTOMAKE might also be updated.

On the other hand, maybe this behaviour qualifies as a bug.

Cheers,

Albert
