[PATCH 0/3] Proposed changes to LAME

Hi there.

I am taking a look at packaging HandBrake for Debian and, while doing it, I
noticed that we (Debian) had some patches against lame that were not applied
in our (lame, upstream) tree.

Some of the patches I saw in Debian's packaging effort that seem to be worth
applying are included in this series.

I did some facelifting here and there, to include more details in the
changelog (for future reference---and tried to dig up some historical facts
for justification of the patches).

I hope that I have not broken anything in other environments (e.g., in
Windows land or operating systems other than Debian/Ubuntu systems), but
since I am not 100% confident with the changes, I am asking here for some
peer-review.

If I don't receive further feedback in 1 week, I will just commit the
changes to the main branch of lame's CVS repo, but, of course, I would
prefer to receive at least one ACK or NACK before doing so.

Regards,
Rogério Brito.

  configure.in: Rewrap for (human) legibility.
  acinclude.m4: Include GTK-1 autoconf directives in build system.
  libmp3lame: Fix possible race condition causing build failures.

This also helps by being diff-friendly if we change only one of the parts of
a long line.

Resurrect knowledge of how to deal with GTK1. This was transplanted back
from aclocal.m4 with a patch provided by Andres Mejia <amejia at debian.org>,
from Debian's packaging of lame, even though the original code is attributed
to Owen Taylor and dated 97-11-3.

Anyway, with this part not lost again, we can easily regenerate autotools'
files with a simple `autoconf -vfi` invocation.

This was discovered in automated builds by the Debian project and the patch
provided is by Andres Mejia <amejia at debian.org>.

Please, note that only part of the patch (the one touching Makefile.am) was
applied, since the changes in Makefile.in should be picked up when
regenerating files with autotools.
