defaults.h (IBM_FLOAT_FORMAT): Macro definition removed. 

2007-05-21  Andreas Krebbel  <krebbel1@de.ibm.com>

	* defaults.h (IBM_FLOAT_FORMAT): Macro definition removed.
	* doc/tm.texi (IBM_FLOAT_FORMAT): Documentation entry removed.
	* real.c (encode_i370_single, decode_i370_single,
	encode_i370_double, decode_i370_double): Functions removed.
	(i370_single_format, i370_double_format): Initializations removed.
	(real_maxval, round_for_format, exact_real_truncate, significand_size):
	Consider the log2_b field to always be one.
