Last (hopefully) soft body fixes:
...
Enable soft body collision clusters by default.
Add option to 'disable collision' button between soft body and rigid body connected by constraint (option was already available between two rigid bodies)

bugfix: add Ghost support for soft bodies, so that they don't collide with ghosts, and can be ghost themselves.

Move the Solaris workaround in btScalar behind the sun define, to only make sun and apple ppc slower:
...
#if defined (__sun) || defined (__sun__) || defined (__sparc) || (defined (__APPLE__) && ! defined (__i386__))
Also includes a fix to uninitialized variable (can cause failing collisions).
If possible, report all changes to extern/bullet2 to http://code.google.com/p/bullet/issues/list

Solaris was having problems with sqrtf and friends again.
...
I changed sqrtf to sqrt in elbeem
in bullet2 I added defines found in floatpatch.h eventually
we should make a "floatpatch.h" that all of blender can use.

Maybe not needed, I was running into some problems though
...
and noticed dos line endings in a bunch of files so ran
dos2unix on everything in bullet2.
Erwin, I noticed there are a few files that do not have
license info in them, couple of quick examples are: btDefaultMotionState.h
btHashMap.h btQuickprof.cpp
could you take a look at add where needed? If you want I can give a list
of files I think should get it added and or just add the standard one
say the one in src/btBulletCollisionCommon.h

add support for Bullet soft body constraints against a Bullet rigid body, as well as 'fixing' it. Just use the existing rigid body joint to use it. For now, it searches the closest node/vertex to the pivot. So you can use multiple constraints/joint to attach a cloth, soft body etc.

fixed some outstanding issues with Bullet soft bodies:
...
1) re-allocate a pool allocator, if one of the soft body collision algorithms is larger than max pool element size
2) manage child shapes properly, and call RemoveReferences on the m_sparsesdf

Allow Bullet soft bodies to be created using a AddObject actuator. Added a fake world coordinate system to game soft bodies, although the vertices are already in world space.
...
Added Bullet/Gimpact concave collision detection to Blender. If your build system isn't updated yet, please add extern/bullet2/src/BulletCollision/Gimpact/*
This allows moving/dynamic concave triangle meshes (decomposing meshes into compound convex shapes, and using 'compound' shapes is still preferred)

Created a KX_SoftBodyDeformer for real-time soft bodies.

Added SetDeformer/GetDeformer() to KX_GameObject.
Store mapping between graphics/soft body vertices (work-in-progress)
Real-time soft body integration is still very premature, but

Bullet logic bug in (de)activation/island management: deactivated 'fantom' objects do merge islands, in particular when connected by constraints. (fantom = object with collision detection but no collision response).

Upgrade to latest Bullet trunk, that is in sync with Blender/extern/bullet2. (except for one define 'WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER')
...
In case someone reads those SVN logs: you can enable some extra broadphase SSE optimizations by replacing WIN32_AVOID_SSE_WHEN_EMBEDDED_INSIDE_BLENDER by WIN32 in extern/bullet2/src/BulletCollision/BroadphaseCollision/btDbvt.h
Thanks to Benoit Bolsee for the upstream patch/contribution.

New: Collision Modifier and Cloth can be at any position on the modifier stack. BUT everytime the vertices count change, they will free themselves and internal build new (they rely on vertex count). Should be no problem anymore with e.g. subsurf modifier before collision modifier (tested). Fix: applied a patch from schlaile to get my bullet additions compiled with gcc 3.3
