llvm (clang) does not support them. Instead, use a global function
with a context created in the external function instead of a nested
function.

See http://bugs.debian.org/742843 for the initial report.

* update MANIFEST
* fix make-release

If there are more processors than requested permutations, some processor
must do nothing. Before, all processors did something, sometimes corrupting
memory...

See http://bugs.debian.org/578550 for errors fixed by this commit

These modules are not used anymore.
The corresponding calls after the rewrite are done directly in C

We do not need to get several values with the same parameters
So, we avoid to check and store the previous state

This function need to be tested on another plateform than linux,
mainly MacOS X.

This will give us a factor about 2.5

The r-code is improved :
- use exact values for afc until 1754 (max that can be
  computed with "long double")
- use per-thread static variables to allow parallel run
  in different threads

No need to define our own.
But we still need to initialize the random generator in each thread

The code is deactivated with "#if 0" to allow ALTree compilation

ResamplingChi2 accepts as last parameter the level of parallelism to use:
- 0 => do not use threaded code
- >0 => use this number of threads (ie 1 is not really usefull
   unless you want to test the threaded code without real parallelism)

Note that this parameter is *OVERWRITTEN* by the
ALTREE_PARALLEL environment variable as soon as it is defined.

The random generator has been changed: the one from the system
was a real bottleneck.

outer functions can choose to allocate memory
with malloc or on their stack
