I think until recently lccwin didn't allow type specifiers in any order,
even though the C standard rather unwisely didn't prohibit this.

There was a problem (now reported as fixed) that involved the new C99
type "long long" but that version, quite correctly, accepts "signed
int short". I am skeptical about the claim, simply because lcc-win32
is based on a well-respected C parser from lcc. I suppose that it is
possible that there is an even older version of lcc-win32 that did
reject the declaration but I doubt it. I think the OP is being
provocative.

Presumably
for historic reasons.

I can't think of any historical reason to reject that syntax and, as I
have said, I would be surprised if (plain) lcc rejected it.

Now lccwin seems to go along with other C compilers rather than take a
stand. So you can now write every declaration in at least N!
different ways.

I think it would have been very unwise to have done anything else. Of
course, a flag "-Wodd-type-specifier-order" might be useful.

On my computer at home 'D' is 68 and 'Q' is 81, no problem there.

On my computer at school, 'D' is 196, 'Q' is 216, and 'D' + 13 is
209, which is 'J'. Problem.

What to do?

It's called programming.

#define LIM 13

char lookup[UCHAR_MAX + 1] = {0};
char lower[] = "abcdefghijklmnopqrstuvwxyz";
char upper[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
int i;
int ch;
assert(UCHAR_MAX < INT_MAX);
for(i = 0; i <= UCHAR_MAX; i++)
{
lookup = i;
}
for(i = 0; i < LIM; i++)

Why using LIM here...

{
lookup[lower] = lower[i + 13];
lookup[lower[i + 13]] = lower;
lookup[upper] = upper[i + 13];
lookup[upper[i + 13]] = upper;

.... but not here?

Bye, Jojo

Sloppiness, my dear fellow - pure sloppiness.

I thought so, but also suspected some deep secret hiding here
