The following simple schoolbook example compiles and runs
with no problems using 'pc' on 4.2bsd, but when I try it on 4.3bsd,

	pc -l foo.p

gives the following result:

-------------------------------------------------------------------

Berkeley Pascal PC -- Version 3.1 (9/7/85)

Tue Dec  2 13:26 1986  foo.p

     1  program FOO(input,output);

     3  type colour = (black,white);
     4  var conv: array[colour] of array[1..5] of char;

     6  begin
     7  	conv[black] := 'white';
     8  	conv[white] := 'black';
     9  	writeln('conv[black] is ', conv[black]);
    10  	writeln('conv[white] is ', conv[white]);
    11  end.
E 7 - Too few subscripts (1 given, 2 required)
E 8 - Type clash: scalar is incompatible with integer
  ... Array index type incompatible with declared index type
  ... Error occurred on index number 2
  ... Error occurred on qualification of conv
E 10 - Too few subscripts (1 given, 2 required)
In program FOO:
  w - variable conv is used but never set

Seems to be a bug here -- has anybody seen it before?

It has the unfortunate consequence that I cannot compile the WICOMO
implementation of Barry Boehms COCOMO cost estimation model anymore.

Strange that it should have passed unnoticed, since this type of
construction must be fairly common.
