Description
#133959 changed behavior of the preprocessor.
test1.f:
c$ !1
endOne-pass compilation succeeds.
$ flang -S -fopenmp test1.f
flang-21: warning: OpenMP support in flang is still experimental [-Wexperimental-option]
$Two-pass compilation via a proprocessed file fails.
$ flang -E -fopenmp test1.f -o test1.pp.f

$ cat test1.pp.f

$The following is another example.

^Before #133959, two-pass compilation succeeded.
@klausler Is this an intended behavior?
