[Xenomai-core] [announce] Xenomai 2.5.6

[Gilles Chanteperdrix <gilles.chanteperdrix@xenomai.org>]

Hi,

Xenomai 2.5.6, a.k.a. "Wormhole Wizards" is available at the usual
place: 
http://download.gna.org/xenomai/stable/xenomai-2.5.6.tar.bz2

It contains mainly bug fixes, for:
- SMP scheduling bugs introduced by the "optimization" in the last
release;
- a cleanup of all architectures kernel threads initializations,
triggered by an issue on powerpc;
- some psos skin updates;
- some analogy updates;
- some compilation issues on ARM and x86 for latest toolchains, and with
uclibc;
- some issues with gdb on blackfin.

And as usual an update of many I-pipe patches, including modifications
to use the latest kernel release to date (2.6.37), and wrappers fixes.

Regards.
