re PR libfortran/33055 (Runtime error in INQUIRE unit existance with -fdefault-integer-8)
2007-08-26 Jerry DeLisle <jvdelisle@gcc.gnu.org>
PR fortran/33055
* trans-io.c (create_dummy_iostat): New function to create a unique
dummy variable expression to use with IOSTAT.
(gfc_trans_inquire): Use the new function to pass unit number error info
to run-time library if a regular IOSTAT variable was not given.
PR libfortran/33055
* io/inquire.c (inquire_via_unit): If inquiring by unit, check for
an error condition from the IOSTAT variable and set EXIST to false if
there was a bad unit number.
