Buggy ssereg float function return on amd64

Hi Tobias,

Actually, the case in which this is a significant issue is *C or C++*
code trying to call FORTRAN's GETARG.  Since libgfortran now has several
versions of getarg (the symbols in the library are named things like
_gfortran_getarg_i4), it is no longer possible for C/C++ code to access
that function via the old usual method of adding an underscore to the
FORTRAN function name, i.e. getarg_().

Is it not possible to include a default version of getarg_ in
libgfortran that is just an alias to _gfortran_getarg_i4 ?  There might
be similar issues for other libgfortran functions, I don't personally know.

best regards,
