highly critical documentation bug

[Paul Zimmermann]

There is a big problem in the GMP documentation: the crucial mpn_divexact_1
function is not documented. With that function, I was able to improve my
code by almost 4%!

As requested in the "Reporting Bugs" section of the GMP manual:

* The GMP version number: 4.2.1
* A test program: info gmp
* A description of what is wrong: mpn_divexact_1 is missing
* If you get a crash: no
* Please do not send core dumps: ok
* The configuration options: ./configure --with-full-documentation
* The name of the compiler and its version: gcc 4.2-latest-snapshot
* The output from running `uname -a': Linux paris.loria.fr 2.6.18-1.2239.fc5 #1 SMP Fri Nov 10 12:51:06 EST 2006 x86_64 x86_64 x86_64 GNU/Linux
* The output from running `./config.guess', and from running
     `./configfsf.guess' (might be the same): x86_64-unknown-linux-gnu
     (it is the same)
* If the bug is related to `configure': no
* If the bug is related to an `asm' file: I guess no

Since it is a highly critical problem, I am waiting soon for a new release
fixing it.
