[Bug fortran/44292] New: [libgfortran ABI breakage] Increase internal size of RECL= of the OPEN statement

[burnus at gcc dot gnu dot org]

libgfortran/io/io.h defines the "struct st_parameter_open" with
  GFC_INTEGER_4 recl_in;

However, the Fortran 95/2003/2008 standard allows any kind of integer
expression and not only the default type. As
http://gcc.gnu.org/ml/fortran/2010-05/msg00302.html shows, gfortran currently
fails if the RECL= is larger than 2 GB.

Expected: The size is increased to GFC_INTEGER_8 to allow large-record access.
