Support the MP library on recent FreeBSD, have it pass relevant tests.
src/ChangeLog addition:
2011-11-26 Aidan Kehoe <kehoea@parhasard.net>
* number-mp.c (bignum_to_string):
Don't overwrite the accumulator we've just set up for this
function.
* number-mp.c (BIGNUM_TO_TYPE):
mp_itom() doesn't necessarily do what this code used to think with
negative numbers, it can treat them as unsigned ints. Subtract
numbers from bignum_zero instead of multiplying them by -1 to
convert them to their negative equivalents.
* number-mp.c (bignum_to_int):
* number-mp.c (bignum_to_uint):
* number-mp.c (bignum_to_long):
* number-mp.c (bignum_to_ulong):
* number-mp.c (bignum_to_double):
Use the changed BIGNUM_TO_TYPE() in these functions.
* number-mp.c (bignum_ceil):
* number-mp.c (bignum_floor):
In these functions, be more careful about rounding to positive and
negative infinity, respectively. Don't use the sign of QUOTIENT
when working out out whether to add or subtract one, rather use
the sign QUOTIENT would have if arbitrary-precision division were
done.
* number-mp.h:
* number-mp.h (MP_GCD):
Wrap #include <mp.h> in BEGIN_C_DECLS/END_C_DECLS.
* number.c (Fbigfloat_get_precision):
* number.c (Fbigfloat_set_precision):
Don't attempt to call XBIGFLOAT_GET_PREC if this build doesn't
support big floats.

/* Hey Emacs, this is -*- C -*- code! */ /* Synched up with: Not synched with FSF. */ /* Think twice before editing this file. Generated automatically by configure. The file startup.el guesses at reasonable values for load-path, exec-path, and lock-directory. This means that if you move emacs and its associated sub-tree to a different place in the filesystem, or to a different machine, you won't have to do anything for it to work. If you define the paths in this file then they will take precedence over any value generated by the heuristic in startup.el. The hardcoded paths will be checked to see if they are valid, in which case they will be used. Otherwise the editor will attempt to make its normal guess. See the NEWS file for a description of the heuristic used to locate the lisp and exec directories at startup time. If you are looking at this file because you are having trouble, then you would be much better off arranging for those heuristics to succeed than defining the paths in this file. ** Let me say that again. If you're editing this file, you're making ** a mistake. Re-read the section on installation in ../etc/NEWS. If it defines anything, this file should define some subset of the following: PATH_PREFIX The default value of `prefix-directory'. This is the default root for everything. PATH_LOADSEARCH The default value of `load-path'. PATH_EXEC The default value of `exec-directory' and `exec-path'. (exec-path also contains the value of whatever is in the PATH environment variable.) PATH_DATA The default value of `data-directory'. This is where architecture-independent files are searched for. PATH_LOCK The name of the directory that contains lock files with which we record what files are being modified in Emacs. This directory should be writable by everyone. If this is specified, the string must end with a slash! PATH_SUPERLOCK The name of the file !!!SuperLock!!! in the lock directory. You probably should let this default... PATH_INFO The default value of `Info-directory-list'. This is where info files are searched for. */
