PACKAGE vs PACKAGE_TARNAME

[infirit]

Hi,

So for a project we wanted to make the tarball different from from the
package name. So we updated AC_INIT and added the tarname and indeed
now the tarball generated changes.

However, we noticed that now the $PACKAGE variable is also changed to
what we set as tarname. Which then caused files being installed in the
wrong place as now $(pkgdatadir) changed as well.

As an example, we changed
AC_INIT([this_is_package], [0.0.1], [http://someurl/])

to
AC_INIT([this_is_package], [0.0.1], [http://someurl/],
[this_is_package_tarname])

I tested this with a small configure.ac and empty Makefile.am. The
example is below.

--
AC_INIT([this_is_package], [0.0.1],[http://someurl/],[this_is_package_tarname])
AM_INIT_AUTOMAKE([1.9 foreign dist-xz no-dist-gzip])

AC_OUTPUT
AC_CONFIG_FILES([Makefile])

echo ${PACKAGE}
echo ${PACKAGE_TARNAME}
--

I put in some echo's at the end of the configure.ac and indeed the
variables $PACKAGE and $PACKAGE_TARNAME *both* change when adding the
tarname to AC_INIT.

Is this a bug in autoconf or are we missing something?
