1.1       root        1: 14 JAN 81:
                      2:        modified rhccomp.c so operators are output as += (for example)
                      3:        instead of =+ . Do a g/token=assignop/ to see the code changes.
                      4:        Then, had to fix the assignop checks.  do g/"[-+<>\*\/|&^%]= "/ to
                      5:        find all of the changes.
                      6:        Also, fixed the =+ (etc..) and initializaton violations in rhccomp.c.

                      8:        Fixed bug in rhccomp.c which messed up goto labels.

                     15:                use malloc(sz) instead of alloc(sz); sz must be even !?
                     16:        fpp.c:          do not #define SMALL
                     17:        rhccomp.c:      HEADLEN: 4 -> 2*sizeof(int)
                     18:                        own alloc() -- calls malloc()
                     19:                        remove outcore.
                     20:        rhsymtab.c:     calloc() -> kalloc() which calls malloc()

                     31:        as third command argument.  (cc.c -> /bin/cc changed also.)

                     44:          therefore no changes needed to rhccomp.c or rhsymtab.c.
                     45:        Use my fpp.c to get /lib/fpp;
