duplicated macros

[Chema Celorio]

I have encountered a problem with aclocal for a long time and have
always wondered if there are any reasons for its behavior.

If aclocal is installed in /abc/bin and aclocal is ran with :
"-I /abc/share/aclocal" it will emit a warning for every macro found
because it will scan the /abc/share/aclocal directory twice. 

Is there a reason for this behavior ? Couldn't it verify that the
"internal directory" is passed in the -I flag and ignore it ? This is a
problem because if you are automating a build, the success of such build
is dependent on the location of the installed aclocal.

[I've just subscribed to the mailing list, could not find the answer on
the web, if this has been answered before, feel free to point me to the
right location]

thanks,
