re PR fortran/40008 (F2008: Add NEWUNIT= for OPEN statement)
2009-06-07 Jerry DeLisle <jvdelisle@gcc.gnu.org>
PR libfortran/40008
* libgfortran.h: Define IOPARM_OPEN_HAS_NEWUNIT.
* io/open.c (st_open): Don't error on negative unit number if NEWUNIT
was specified. If NEWUNIT is specified, call new function to get the
unique unit number and assign it.
* io/io.h (st_parameter_open): Add pointer to newunit. Add prototype for
next_available_newunit. Add prototype for new function,
get_unique_unit_number.
* io/unit.c: Declare next_available_newunit. Define the first newunit
number. (init_units): Initialize next_available_unit.
(get_unique_unit_number): New function. Fix whitespace and comments.
* io/transfer.c (data_transfer_init): Update error message to not be
specific to OPEN statements.
