--- Comment #2 from Jakub Jelinek  ---
See e.g. OpenMP 5.0 2.9.1 chapter, or OpenMP 4.5 2.6 chapter.
for (init-expr; test-expr; incr-expr) structured-block
init-expr
One of the following:
var = lb
integer-type var = lb
random-access-iterator-type var = lb
pointer-type var = lb
...
incr-expr
One of the following:
++var
var++
- - var
var - -
var += incr
var - = incr
var = var + incr
var = incr + var
var = var - incr

So both your init-expr and incr-expr are invalid.

That is not valid OpenMP, so it is perfectly fine it is rejected.
In OpenMP, you can't use arbitrary for (...) following the various loop
pragmas, they have various restrictions.
