stamp-h numbering

[Kevin Ryde]

I think AM_CONFIG_HEADER always puts a number on the stamp-h filename,
but it seems handle_configure doesn't bother with a number if there's
only one such stamp (or only one in the current directory, I'm not
sure).  This ends up inducing a re-run of config.status on a "make
all" because config.h depends on stamp-h whereas stamp-h1 was created
by config.status.  This afflicts automake 1.5, and I think the current
cvs too.

Changing automake.in to match m4/header.m4 is pretty easy (below), but
maybe an unnumbered stamp was intended and instead m4/header.m4 should
be fixed.

        * automake.in (handle_configure): Always put a number on $stamp_name,
        to match AM_CONFIG_HEADER.
