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

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.

It suggests to me that you need to read a book on Fortran or
the Standard.  It also fails for writing to unit=6.

laptop:kargl[207] gfortran44 -o z a.f90 
a.f90:2.11:

write(*,'(I)') i
           1
Error: Nonnegative width required in format string at (1)


You can get want you by using 'write(strcounter,*) someint'
or 'write(strcounter,'(I0)') someint'.

You're welcomed.  With my suggested fixes, you'll actually
have standard conforming code.
