LAME is an MPEG Audio Layer III (MP3) encoder licensed under the LGPL.

Today, LAME is considered the best MP3 encoder at mid-high bitrates and at VBR, mostly thanks to the dedicated work of its developers and the open source licensing model that allowed the project to tap into engineering resources from all around the world. Both quality and speed improvements are still happening, probably making LAME the only MP3 encoder still being actively developed.

    Don't include the debian directory as one that is needed during builds. Patch taken from Debian's packaging of lame.
    Resurrect Owen Taylor's code dated from 97-11-3 to properly deal with GTK1. This was transplanted back from aclocal.m4 with a patch provided by Andres Mejia. This change makes it easy to regenerate autotools' files with a simple invocation of autoconf -vfi.
    Fix possible race condition causing build failures in libmp3lame. Discovered in automated builds by the Debian project with patch provided by Andres Mejia.
