bunch of sytnax errors after #include btSoftBody.h

[main_vertex]

Hello Guys,

I'm new to Bullet library.
Maybe you will know how to fix problem I'm facing.

In visual studio 2005 I compiled examples without errors.
Everything seems to work fine. I've got all lib files included into my project.
I have also implemented 'hello world' example into third party software as a plugin.
Movement is translated, my object is moving as I would expect.
Main interest of mine is to use soft bodies dynamics, so I included "btSoftBody.h" or "BulletSoftBody\btSoftRigidDynamicsWorld.h".
After this explosions of errors is shwing up.
First error says that there is a syntax error in included file.
I believe, there is no syntax errors, because library is used in games,
by other people and it seems very solid.

I would like to as for any help, or where to look for it.
Thank you very much for you help.

Regards.
