acinclude.m4 help?

[Jason Gerfen]

I am pretty sure I am doing this according to the manual pages but it is 
still not working.  I am attempting to modify an existing acinclude.m4 
file to include some functionality I wrote into an existing shared object.

Now that I have tested the functionality of that code I am attempting to 
allow easier configuration through the ./configure shell script.

Here is the bit I am adding, but when I run aclocal, autoconf, automake 
the option does not appear in the ./configure --help menu, nor does it 
link against the -lldap libs.  Any help, pointers, tips, tutorials are 
appreciated.

acinclude.m4

       AC_ARG_ENABLE(ldap,[

[enable_ldap="no"])

       if test "$enable_ldap" = "yes"; then
               AC_DEFINE(_LIBLDAP,1,[Define if you require OpenLDAP 
support.])
