Update.
1999-03-09  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* stdlib/strtod.c (round_and_return): Fix rounding of denormals.
	(DENORM_EXP): New define.  Use it as the exponent for a denormal.
	* stdlib/strtold.c: Moved to ...
	* sysdeps/generic/strtold.c: ... here.
	* sysdeps/m68k/strtold.c: New file.

1999-03-09  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* stdio-common/printf_fphex.c (__printf_fphex): Print no decimal
	point if the precision is zero, even if the mantissa is non-zero.
