You should add the contents of `m4/argz.m4' to `aclocal.m4' messages

[Alexandre Duret-Lutz]

Hi folks,

While trying to understand another problem in one of my projects,
I came to this case where libtoolize tells different things when run
twice.  The second time it told me this:

libtoolize: You should add the contents of `m4/argz.m4' to `aclocal.m4'.
libtoolize: You should add the contents of `m4/lt~obsolete.m4' to `aclocal.m4'.

IMHO, these messages are confusing for three reasons:
1. They magically appeared during the second run.
2. These files contains macros that are not used _this_ configure, so need
   not be added to aclocal.m4.
3. In this case aclocal.m4 is generated by aclocal, so the user should never
   be asked to touch this file.

Is there a way to get rid of these messages in order not to
confuse people?  For instance maybe libtoolize could guess that
aclocal is being used, checking the presence of ACLOCAL_AMFLAGS
or looking into aclocal.m4?



Here is a test case with today's HEAD versions of Autoconf,
Automake, and Libtool (but the project I'm working on normally
uses the latest releases, hence the old syntax):
