# Shell script to build shared library versions of the modules; since
# the change to the *ahem* "proper" import/export mechanism, this script
# is much simpler.  It handles PowerPC and x86, too.
#
# This is called by the Modules/Makefile as $(LDSHARED):
#
# $(LDSHARED) foomodule.o -o foomodule$(SO)
#
# Could also be called as:
#
# $(LDSHARED)  readline.o  -L/boot/home/config/lib -lreadline -ltermcap \
# -o readline$(SO)
#
# so we need to preserve the arguments, sort of.

# Make sure we got reasonable arguments.
