WANT_ARITH is defined as:
...
#define WANT_ARITH (WANT_INT | WANT_FLOAT | WANT_VECTOR_OR_COMPLEX)
...
so the patch effectively removes WANT_VECTOR_OR_COMPLEX. AFAIU the COMPLEX case
is already handled at this point, so there shouldn't be any effect for those.
This patch brings back the old error message:
...
test.c: In function ‘void foo()’:
test.c:4:5: error: no pre-increment operator for type
++v;
