History of Major Changes to SoftFloat, up to Release 2a

Release 2a (1998 December)
-- Added functions to convert between 64-bit integers (int64) and all
supported floating-point formats.
-- Fixed a bug in all 64-bit-version square root functions except
`float32_sqrt' that caused the result sometimes to be off by 1 unit in
the last place (1 ulp) from what it should be. (Bug discovered by Paul
Donahue.)
-- Improved the makefiles.

Release 2 (1997 June)
-- Created the 64-bit (bits64) version, adding the floatx80 and float128
formats.
-- Changed the source directory structure, splitting the sources into a
`bits32' and a `bits64' version. Renamed `environment.h' to `milieu.h'
(to avoid confusion with environment variables).
-- Fixed a small error that caused `float64_round_to_int' often to round the
wrong way in nearest/even mode when the operand was between 2^20 and 2^21
and halfway between two integers.

Release 1a (1996 July)
-- Corrected a mistake that caused borderline underflow cases not to raise
the underflow flag when they should have. (Problem reported by Doug
Priest.)
-- Added the `float_detect_tininess' variable to control whether tininess is
detected before or after rounding.
