I installed Fortran V2 under Ultrix V4.0 (on a DECstation 2100) using the same
tape that I used to install it under V3.1. Recently I noticed that f77 points
to f772.1, in other words f77 was V2.0 under Ultrix V3.1 and now is V2.1
under ultrix V4.0. Looking at the links in /usr/bin:

f77 -> f772.1 -> ../lib/cmplrs/cc2.1/driver -> driver2.1
        cc2.1 -> ../lib/cmplrs/cc2.1/driver -> driver2.1
cc  ->  cc2.0 -> ../lib/cmplrs/cc2.0/driver -> driver2.0

It seems that the Fortran installation also upgraded the C-compiler to version
2.1, but cc still points to the old C-compiler (v2.0). I checked the disk
usage on ../lib/cmplrs/cc2.0 to find 6 Meg there and on ../lib/cmplrs/cc2.1 to
find 7.3 Meg there. Finally the question:

Is it safe to link cc to cc2.1? For instance can I rebuild the kernel using
cc2.1. The followup question is then, whether I can delete the cmplrs/cc2.0
directory to save disk space (I run with a standalone system with two internal
Maxtor 200 Meg disks, and the system disk is tight for space).
