R problems with lapack with gfortran
...ad_ (double *small, double *large);
void drscl_ (int *n, double *sa, double *sx, int *incx);
void dlatrs_ (char *uplo, char *trans, char *diag, char *normin, int *n,
double *a, int *lda, double *x, double *scale, double *cnorm, int *info,
size_t uplo_len, size_t trans_len, size_t diag_len, size_t normin_len);
which could serve as the basis for adjusting the calling sequence
for the C bindings to what the compiler expects.
I checked, and it appears that at least ifort uses the same convention
as gfortran 8/9 regarding character argument passing.
