Ok for trunk then.

While I agree this might trigger compatibility issues with old
debuggers, I don't know what to do assuming this change is not
acceptable: should we add a kludge in add_scalar_info in order to force
unsignedness when generating debugging information for Fortran?
Here is a data point: I tried to debug gfortran.dg/array_function_2.f90
build with my patches compiler for x86_64-linux with a GDB from an old GNAT
Pro release (5.03a1, from 2005):
(gdb) b array_function_2.f90:24
(gdb) r
(gdb) ptype q_in
type = real*8 (0:-1,-6:-1)
With a recent GDB, I have instead:
(gdb) ptype q_in
type = real(kind=8) (0:*,-6:*)
Given that the only thing that my patches changed in the debug information
for this example is the encoding of the arrays' lower bounds, everything
looks fine, here.
