Known bug in some versions of autoconf. See attached script for building 
MPFR for example how to workaround the problem (and possibly 
additionally build a packages for DJGPP distribution).

This is DJGPP port of MPFR-$version.

The MPFR library is a C library for multiple-precision floating-point
computations with correct rounding. MPFR requires GMP for use. It is also
required to install MPFR after GMP, as it may replaces part of GMP files

See README and http://www.mpfr.org for more information.

Building from sources
=====================

LFN support is required for building MPFR for DJGPP. I built MPFR
using GCC-$gcc_ver under Windows Vista Business SP2. DJGPP port of GMP-$gmp_ver
were used when building MPFR-$version. One may need to to rebuild MPFR
if different enough GMP version is being used. 

Sources in mpfr${djver2}s.zip are preconfigured for target i386-pc-msdosdjgpp.
Simply running configure script with needed parameters should be enough
to reconfigure if needed.

To build MPFR run 'make'.

To run tests of the MPFR, run 'make check'

To install MPFR run 'make install prefix=where_to_install' (replace
'where_to_install' with real value).
