PR libfortran/37839 * trans-io.c (gfc_build_io_library_fndecls): Decrease pad size back to 16 pointers plus 32 integers. Don't use max integer kind alignment, only gfc_intio_kind's alignment. (gfc_trans_inquire): Only set flags2 if mask2 is non-zero. * ioparm.def: Fix order, bitmasks and types of inquire round, sign and pending fields. Move u in dt before id. * io.c (gfc_free_inquire): Free decimal and size exprs. (match_inquire_element): Match size instead of matching blank twice. (gfc_resolve_inquire): Resolve size. * gfortran.dg/f2003_inquire_1.f03: New test. * gfortran.dg/f2003_io_1.f03: Remove xfail. * gfortran.dg/f2003_io_4.f03: Likewise. * gfortran.dg/f2003_io_5.f03: Likewise. * gfortran.dg/f2003_io_6.f03: Likewise. * gfortran.dg/f2003_io_7.f03: Likewise. * io/io.h (IOPARM_INQUIRE_HAS_ROUND, IOPARM_INQUIRE_HAS_SIGN, IOPARM_INQUIRE_HAS_PENDING): Adjust values. (st_parameter_inquire): Reorder and fix types of round, sign and pending fields. (st_parameter_43, st_parameter_44): Removed. (st_parameter_dt): Put back struct definition directly to u.p declaration. Change type of u.p.size_used from gfc_offset to GFC_IO_INT. Decrease back size of u.pad to 16 pointers and 32 ints. Put id, pos, asynchronous, blank, decimal, delim, pad, round and sign fields after the union. * io/inquire.c (inquire_via_unit, inquire_via_filename): Only read flags2 if it is defined. * io/transfer.c (read_sf, read_block_form, write_block): Cast additions to size_used to GFC_IO_INT instead of gfc_offset. (data_transfer_init): Clear whole u.p struct. Adjust for moving id, pos, asynchronous, blank, decimal, delim, pad, round and sign fields from u.p directly into st_parameter_dt. (finalize_transfer): Don't cast size_used to GFC_IO_INT. * io/file_pos.c (st_endfile): Clear whole u.p struct. From-SVN: r142111
