        * ginclude/float.h: Rename DECnn_DEN to DECnn_SUBNORMAL_MIN.
        * real.c (decimal_single_format): Correct values of emin and emax.
        (decimal_double_format): Ditto.
        (decimal_quad_format): Ditto.
        * c-cppbuiltin.c (builtin_define_decimal_float_constants): Adjust
        computation of DECnn_MIN and DECnn_MAX for corrected values of
        emin and emax.  Define __DECnn_SUBNORMAL_MIN__ instead of
        __DECnn_MIN__, and adjust its computation for the corrected value
        of emin.

        * gcc.dg/dfp/decfloat-constants.c: Check for DECnn_SUBNORMAL_MIN
        instead of DECnn_DEN.  Support -DDBG to list lines that fail.
