Submitted By:            Kevin Day <kevin AT kevux DOT org>
Date:                    2006-08-07
Initial Package Version: 4.1.1
Upstream Status:         uClibc specific
Description:             The fix from the HLFS project for getting uClibc support.
The original patch was undocumented, but I imagine it was done by: Robert Connellly <robert at linuxfromscratch dot org> (ashes)
