Testcase for List-directed read

By default gtk_init calls setlocale, so if the locale is set to one that uses
comma for decimal, the attached code fails to read the numbers after the
decimal in the case with the point. However neither before or after is the
cases with the comma handled as a decimal:

james@amarice-4 Dev $ export LC_ALL=de_DE.UTF8
james@amarice-4 Dev $ ./a.out 
   100.34560   100.0
   100.0   100.0
james@amarice-4 Dev $ export LC_ALL=
james@amarice-4 Dev $ ./a.out 
   100.34560   100.0
   100.34560   100.0
james@amarice-4 Dev $ 


N.B. I do have a work-around for gtk-fortran by adding a call to
gtk_disable_setlocale, which I will add to the gtk_init routine.

Code demonstrating the problem



When I run the attached program with gfortran (4.7.2), the length appears to be
