R problems with lapack with gfortran

Hi, Thomas, Tomas,

Doesn't this issue demonstrate the warning and advice given in the  last paragraph of section 6.6 
of the "Writing R Extensions" manual:

<ref>
Passing character strings from C to Fortran or vice versa is not portable (and to Fortran 90 or later is even less so). We have found that it helps to ensure that a C string to be passed is followed by several nuls (and not just the one needed as a C terminator). But for maximal portability character strings in Fortran should be avoided.
</ref>

Avoid.

Hi Tomas,

thanks a lot for your analysis.  I have created
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90329
for this, and put you in CC (if your e-mail address
for GCC bugzilla is still current).

Regards

	Thomas
