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.
