Just when you thought it was safe to add! An old bug that was
supposedly fixed in MPW C ver 2.0.2 turns out to have only been
wounded.
The following is the shortest program that I have found that exibits
the problem:
main(argc,argv)
int argc;
char *argv[];
{
double skuz[10];
double foo=4;
skuz[5]= 2.3;
skuz[5] += 4*foo; /* this add fails */
printf("skuz= %g\r",skuz[5]);
}
The value printed is 2.3, which is the symptom of the old bug. It is just
a little harder to make it appear now.
I am getting a little tired of this bug. Does anyone know when MPW 3.0
is due out? I am really looking forward to a whole new round of bugs.

No, I haven't reported the bug to Apple.

That's not a bug, this is a bug... short i,j,k,ok,l; Seems you can't have a varible named 'ok'. Ran into this one porting gnuchess. Arrgh.

This is only true if you include dialog.h. ok is a constant (as in the default
button). I agree its a pain, Apple should have #defined all of those constants
in mixed or uppercase. But then again Apple should also have defined ints
to be 16 bits (uh-oh, I hear Larry Rosenstein saying.."arrgh! not again!" :-)
[yes, I have been working all weekend with MPW C... (*Sigh*)]

The problem you are running into here is that there are a couple of constants predeclared by the Dialog Manager as per Inside Mac for ok and cancel (named, interestingly enough, ok and cancel). You're trying to redeclare something here and the compiler, quite correctly, is telling you that you can't. If you don't bring in those libraries and interfaces, ok will be a valid identifier.
