Help with path expansion

[Mike Gran]

Hi-

I have this snippet of autoconf file that generates a warning.

    AC_INIT([blammo],[0.0])

    pkgsitedir="$datadir/$PACKAGE_NAME"

    AC_MSG_WARN([]
       [The modules will be installed in ${pkgsitedir}.])

When I run it, I get the text

    configure: WARNING:
       The modules will be installed in ${datarootdir}/blammo.

Is there a way to have this warning output the full path, e.g.
for it to say something like

       The modules will be installed in /usr/local/share/blammo

(assuming that /usr/local/share/ is datarootdir)

Thanks,

Mike Gran
