well, currently AC_BEFORE([FOO], [BAR]) makes sure that BAR was not
yet expanded. It is supposed that this macro is called from FOO;
perhaps we should issue a warning if it is not. The macro ignores
its first parameter.
Actually, it is a trivial application of m4_provide_if (a.k.a.
AC_PROVIDE_IFELSE). Perhaps we could make the confusing
AC_BEFORE as obsolete, replacing it by m4_provide_if (which would
have to be documented for this purpose).

Then redefine AC_PROG_INSTALL so that it issues the warning before
calling the original code:
----- snip --------
AC_INIT([foo], [1.0], [EMAIL PROTECTED])
AC_DEFUN([gl_RELOCATABLE],
[do something
m4_define([AC_PROG_INSTALL],
[m4_warning([AC_PROG_INSTALL was called after gl_RELOCATABLE])]
m4_defn([AC_PROG_INSTALL]))
])
AC_PROG_INSTALL
gl_RELOCATABLE
AC_PROG_INSTALL
----- snip --------
Does this solve your problem?
Have a nice day,
Stepan
