I have no strong opinion on this, I followed the -Wintrinsic-shadow example, and I'm happy to change things. Note however, that even the Fortran standard recommends the ONLY option for example for intrinsic modules, to guarantee that a program is portable to other processors and future versions of the standard, i.e. to avoid potential name conflicts (see Note 15.1 in F2003 standard).
