It's probably more than enough just following the note in the header
of the source:

    DL> /* W.J. Antel Jr.  12/12/96 ** Compile with gnu's gcc: gcc
    DL> hello.m -lobjc */

You added the "-c" switch, that means "do only the compilation step,
producing an 'object' file ending in .o". The produced 'hello.o' is
not an executable, it needs to be linked against runtime libraries...

hth,
ciao, lele.
