# DESCRIPTION
# Generic rules for extracting objects from GNU libraries.
# Subdirectory Makefiles for specific libraries should
# set GNULIBDIR and GNULIBRARY and include this file.
#
  
# Ask the compiler driver for the version (e.g. gcc-2.6) and
# machine (e.g. powerpc-wrs-vxworksae). This info may
# be used by subdirectory Makefiles to compute GNULIBDIR.
