System calls in SunFortran 1.1 under SunOS4.0?

I wonder if anyone could help me with the following "known" problem. We
are porting all our software written in Fortran on a new SUN 4/280 running
SunOS 4.0 and there seems to be no way to make system calls!!!
Try to compile the following fortran program:
program test
call system('pwd')
stop
end
and then f77 test.f, you will get the following error message:
test.f
MAIN test:
ld: Undefined symbol
_units
Is there a patch out there for the libU77.a or is there a way to define
_units. I tried to define it in a small c program and it worked properly
but we have tried it with a more complex program and it blows up at
execution time.
I don't understand how a company like Sun Microsystems can release such an
incomplete product without even testing it.
Note: This problem is known and documented in the Software Technical
Bulletin of September 1988 page 1875 but there is no work around.
I have also called the Sun Hotline in California but I am still waiting
for them to reply.
Thanks in advance,
