I just got SC 6.1 from the net and much to my suprise gcc would not
compile it while SUN OS3.5 cc would.

A little tracking produced the problem in:
**********************************************************************
#define ctrl(a) ('a'&037)

used as:
        switch (ch)
        case  ctrl(r):
            break;
        case ctrl(z):
            break;
**********************************************************************
I would say that this is not supposed to compile yet SUN cc does OK while
GCC doesn't.  Do wiser minds have comments?
