Aztec C compiler bug(?)

[Craig Knelsen]

#include        <quickdraw.h>

    register ControlHandle        p;

    f((*p)->contrlTitle);

c.c: line 9: error 29: illegal use of structure:

Compiler:        Aztec C 1.06G for the Macintosh

        The problem seems to result from the fact that Aztec changed the
declaration of the member 'contrlTitle' in control.h:

        1.06D release:
                        char        contrlTitle[1];
        1.06G release:
                        Str255        contrlTitle;

where Str255 is a typedef for: char *

        I have tried this example under the Vax 4.2bsd and Sun 2.0 compilers
with no complaints from either. Changing the declaration back to what it
was in the 1.06D release makes the problem disappear. Removing the register
storage class declaration doesn't make a difference as far as the error is
concerned.
