Subject: [MPFR] MPFR-2.4.0 Release Candidate

The release of MPFR 2.4.0 ("andouillette sauce moutarde") is imminent. 
Please help to make this release as good as possible by downloading and 
testing this release candidate:

The MD5's:
d0632e2f43081f8c1c438471abce3f4b  mpfr-2.4.0-rc1.tar.lzma
5d69b25a675b3b336c9cf34a9d9ce305  mpfr-2.4.0-rc1.tar.bz2
a0bf1b858fcb48f0d24ffb61642eed87  mpfr-2.4.0-rc1.tar.gz

The signatures:

Changes from version 2.3.2 to version 2.4.0:
- MPFR is now a GNU package.
- Changes in the behavior of mpfr_strtofr and in its documentation
  concerning particular cases where the code and the documentation
  did not match; this change is also present in MPFR 2.3.1.
- Behavior of mpfr_check_range changed: if the value is an inexact
  infinity, the overflow flag is set (in case it was lost); this
  change is also present in MPFR 2.3.2.
- Function mpfr_init_gmp_rand (only defined when building MPFR without
  the --with-gmp-build configure option) is no longer defined at all.
  This function was private and not documented, and was used only in
  the MPFR test suite. User code that calls it is regarded as broken
  and may fail as a consequence. Running the old test suite against
  MPFR 2.4.0 may also fail.
- New functions:
  * between a MPFR number and a double: mpfr_add_d, mpfr_sub_d,
    mpfr_d_sub, mpfr_mul_d, mpfr_div_d, mpfr_d_div,
  * formatted input/output:
    mpfr_printf, mpfr_fprintf, mpfr_vprintf, mpfr_vfprintf,
    mpfr_sprintf, mpfr_snprintf, mpfr_vsprintf, mpfr_vsnprintf,
    mpfr_asprintf, mpfr_vasprintf.
  * mpfr_sinh_cosh, mpfr_li2, mpfr_modf, mpfr_fmod, mpfr_rec_sqrt.
- Configure test for TLS support.
- Get default $CC and $CFLAGS from gmp.h (__GMP_CC / __GMP_CFLAGS,
  which are available as of GMP 4.2.3).
- Documented the fact that mpfr_random and mpfr_random2 will be
  suppressed in the next release, and that the specification of
  mpfr_eq may change in the next release (for compatibility with
  the mpf layer of GMP).
- Bug fixes.

Please send success and failure reports  with "./config.guess" output to  
<mpfr at>.

If no problems are found, MPFR 2.4.0 ("andouillette sauce moutarde") should be
released around 2009-01-12.
