This is announcement of DJGPP port of MPFR-3.1.6

What is MPFR (fragment from MPFR documentation)
===============================================

MPFR is a portable library written in C for arbitrary precision
arithmetic on floating-point numbers. It is based on the GNU MP
library. It aims to extend the class of floating-point numbers
provided by the GNU MP library by a precise semantics. The main
differences with the mpf class from GNU MP are:

     * the mpfr code is portable, i.e. the result of any operation
       does not depend (or should not) on the machine word size
       mp_bits_per_limb (32 or 64 on most machines);
     * the precision in bits can be set exactly to any valid value
       for each variable (including very small precision);
     * mpfr provides the four rounding modes from the IEEE 754-1985
       standard.

In particular, with a precision of 53 bits, mpfr should be able
to exactly reproduce all computations with double-precision machine
floating-point numbers (double type in C), except the default
exponent range is much wider and subnormal numbers are not
implemented but can be emulated.

This version of MPFR is released under the GNU Lesser General
Public License. It is permitted to link MPFR to non-free programs,
as long as when distributing them the MPFR source code and a means
to re-link with a modified MPFR library is provided.

Configure option --disable-thread-safe added when configuring mpfr for DJGPP build.
