Creating an archive with your object files and ranlib'ing it is not really
much faster than doing a cc ${OBJECTS}, since ld still needs to go through
each module. If you really want to do this, though, you will need
to do a bit more than just ld <archive_file>.
ld only loads archive members necessary to satisfy any undefined externals.
either leave your main module out of the archive and
cc -o int main.o tempint
or use the -u flag of ld: ld -u main -o int tempint

You should almost always use cc instead of ld, since there are several
switches that need to be used in the ld invocation that cc provides,
which are dependent on the implementation, whether you are using a floating
point simulator and/or profiling, overlays, etc.
