((int *) p)++;
is no longer accepted for C++ and will not be accepted for C and
Objective-C in a future version.
Unfortunately I don't know the proper fix, but I'm hoping I'll get an
answer to that question tomorrow in the gcc-help mailing list.
How about:
char *p;
...
int *q = (int *) p;
q++;
p = (char *) q;
That would have the same net effect and is accepted by gcc 4.2.3,
which does not accept the original construct.
