modifications:

done:
- context moveable
- context simple class/not a template
- context doesn't manage the stack (done) -> user has to safe pair of 
context and stack
- SSE2 control word preserved in i386 asm too
- bool context::finished() const indicates if context finished (context 
is unwound)
- function associated with context stored on top of the stack - thx do 
GIovanni
- function pointer or function-object can be used with context

todo:
- re-factoring C-API: boost_fcontext_make(), boost_fcontext_jump()
- test-app for UNIX signals + boost::context
- support for stack-unwinding using DWARF facilities (eh_frame) -> 
investigation if possible

regarding to stack unwinding: the user has the possibility to check if 
the function called by context has finished (stack was cleaned up).
The user can decide what to do - throw stack away, do some sophisticated 
work (jump back into stack and throw exception) or
if possible and implementable use a unwind() function using DWARF 
facilities (eh_frame) to unwind the stack.
