This is quite likely correct. The current gfortran docs [1] list

As an existing package I suspect that it already calls the R RNG, but the
default RNG changed [1] so you need to call
RNGkind(sample.kind = "Rounding") before calling set.seed in your test code to
compare with old results.

Hi.
If it helps, I call the R RNG from Fortran in my Delaporte package
[1], also using iso_c_bindings. Specifically, I have the following C
code [2]:
void F77_SUB(unifrnd) (int *n, double *x){
GetRNGstate();
for (int i = 0; i < *n; ++i){
*(x + i) = unif_rand();
}
PutRNGstate();
}
and call it in
