-# Manuel Novoa III Jan 2001
-#
-# The purpose of this script is to extract the object files from libgcc.a
-# that are needed by the shared uClibc so that they won't be linked with
-# each application.
-#
-# I'm sure people with better shell programming skills can improve this.
-# Feel free! ;-) At this point though, it gets the job done for me.
-#
-# Possible problems (paranioa mode): Are any of the objects in libgcc.a
-# needed to actually load the shared library on any archs?
-
-#Enable this when debugging
-#set -x
