+# Becuase we can be compiling for either elf or coff, we need to create
+# special versions of libgcc.a. It IS possible for this not to be done
+# and let the SCO linker transform the coff objects (which are created
+# by default) into elf objects. However, this is inefficient. So,
+# we create a libgcc-elf.a, which is used in the specs in sco5.h.
+# These are the rules for doing that.
+#
+# NOTE: This is duplicated directly from Makefile.in. If you change it
+# there, be sure to change things here!
