# 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.
