[R] R's RNG produced garbage when called from f77 (Irix)

[Liaw, Andy]

OK, I seemed to have solve the problem.  As also pointed out in the same
section of the R-exts manual, "Passing values via argument is safer."  I
just change the C function from double with no argument to void with double
* (and changed the Fortran calls from function to subroutine).  Now it seems
to run fine.  Sorry to bother everyone.

Cheers,
Andy
