# 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!
