R devel - Mar 2009 - dger_ in BLAS definition

I'm developing some software and running into compiling warning:
conditionals.c:104: warning: passing argument 4 of 'dger_' discards
qualifiers from pointer target type
conditionals.c:104: warning: passing argument 6 of 'dger_' discards
qualifiers from pointer target type

the netlib documentation states that the arguments x and y should be
unchanged on exit.  Should should imply the defintion:

F77_NAME(dger)(const int * const m, const int * const n, const double *
const alpha,
           double const * const x, const int *const incx,
           double const * const y, const int *const incy,
           double * const a, const int * const lda);

the current definition is missing the appropriate consts:
F77_NAME(dger)(const int *m, const int *n, const double *alpha,
           double *x, const int *incx,
           double *y, const int *incy,
           double *a, const int *lda);

I don't want my code compiling with warnings that shouldn't be there. 
Are
there suggestions of how to work around this?

Thanks

Yes x and y arguments are unchanged on exit, cf.
http://www.mathkeisan.com/UsersGuide/man/dger.html

This is the work of the R core team to update those files, but I fear  
there are other functions which are not well declared.

Will you agree to take a look at the BLAS.h file? It will be very  
useful if you have time to do it.

(A year ago, I check the lapack.h and there was some wrong  
declarations like zgecon function.)
