* 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.
