I'm having difficulties updating my package eha: When I run standard checks 'at home' everything is fine, but 'CRAN-submissions' reports (among other things):

geomsup.f:324:9: warning: type of ‘dgemv’ does not match original declaration [-Wlto-type-mismatch]
  324 |      &     one, score, ione)
      |         ^
/home/tmp/R-d-gcc-LTO/include/R_ext/BLAS.h:107:1: note: type mismatch in parameter 12
  107 | F77_NAME(dgemv)(const char *trans, const int *m, const int *n,
      | ^

This is odd since the LAPACK subroutine dgemv takes only 11 parameters. However, in include/R_ext/BLAS.h we have

F77_NAME(dgemv)(const char *trans, const int *m, const int *n,
                const double *alpha, const double *a, const int *lda,
                const double *x, const int *incx, const double *beta,
                double *y, const int *incy FCLEN);

with a 12th parameter FCLEN?? How am I supposed to fix this, and what the ... is FCLEN? googling leads to nothing useful (for me). It seems as if R is redefining some standard LAPACK routines.

Also a note I do not understand (in this context):

note: type ‘void’ should match type ‘long int’

Any help is much appreciated.

Best, Göran

PS. How can I trigger these Warnings 'at home'?
