[Bug fortran/43158] New: No default integer descriptor width

[wchemelewski at gmail dot com]

With the following code:

INTEGER :: someint
CHARACTER (LEN=40) :: strcounter
WRITE(strcounter,'(I)') someint

The error message is generated:

WRITE(strcounter,'(I)') someint
1
Error: Nonnegative width required in format string at (1)

Which to me just suggests that gfortran does not have the (i believe) standard
behavior of automatically assigning a width to the format descriptor based on
the given integer.  However, this only appears to be a problem when using a
character variable/internal file.
