fcsys:

This directory contains links to those files in ubc/sys that are needed
for the F77 distribution. Most are already present in binary form in
the bin directory, but the sources are provided just in case they are 
needed.

Each of the routines present in this directory 
can be re-compiled by a command of the form:

cc prog.c ../lib/libw.a
mv a.out /bin/prog 

if libw.a has been installed in /lib then one need only specify it
as -lw. some of the other shell files assume that is the case.
