# This is annoying.  The linker won't accept a static lib whose
# modification date is later than when its internal table was last updated
# with 'ranlib'.  So whenever we get a fresh copy of the lib from cvs, it
# gets a new date, making it invalid for linking.  We can run ranlib on the
# lib, but then cvs will think it changed and get a bounce next time we
# update.  So we have to copy the libs into a temp dir, run ranlib on them,
# then use from there.
