behavior and compiler extensions based on UB (in particular -fwrapv).
MPFR doesn't use such extensions, but these macros will be used by
3rd-party code, where such extensions may be required.

macros for GCC, in order to avoid warnings in programs that use MPFR and
are compiled with -Wconversion (suggestion by Andreas Enge); such casts
are OK since if X is a constant expression, then (unsigned long) X is
also a constant expression, so that the optimizations still work.
Reformatted these macros.

by mpfr_cmp_si), when the evaluation of the first argument yields
side effects and the second argument is a constant expression with
the value 0.

that an internal overflow/underflow doesn't occur. In theory, such
an exception is possible, but only if q has a huge numerator or
denominator. This is not supported (note: other problems may occur
first, such as insufficient memory).

[tests/tgmpop.c] Added corresponding testcases.

mpfr_sub_z could fail in a reduced exponent range. Fixed.

it be in the API?) that computes y = RND(x*n/d), where n and d are mpz
integers. Changed mpfr_mul_q and mpfr_div_q to use this function.
Note: the code of the general case is currently the same as the old
mpfr_mul_q/mpfr_div_q code, thus needs to be fixed.

* Added directories and moved related files into them:
- src for the MPFR source files (to build the library).
- doc for documentation files (except INSTALL, README...).
- tools for various tools (scripts) and mbench.
- tune for tuneup-related source files.
- other for other source files (not distributed in tarballs).
Existing directories:
- tests for the source files of the test suite (make check).
- examples for examples.
- m4 for m4 files.
* Renamed configure.in to configure.ac.
* Added/updated Makefile.am files where needed.
* Updated acinclude.m4 and configure.ac (AC_CONFIG_FILES line).
* Updated the documentation (INSTALL, README, doc/README.dev and
doc/mpfr.texi).
* Updated NEWS and TODO.
* Updated the scripts now in tools.
The following script was used:
#!/usr/bin/env zsh
svn mkdir doc other src tools tune
svn mv ${${(M)$(sed -n '/libmpfr_la_SOURCES/,/[^\]$/p' \
Makefile.am):#*.[ch]}:#get_patches.c} mparam_h.in \

svn mv FAQ.html README.dev algorithm* faq.xsl fdl.texi mpfr.texi \

svn mv configure.in configure.ac
svn cp Makefile.am src/Makefile.am
