Hi,

my previous message was incomplete - sorry:

The modifications requested by the reviewers are incorporated into 
boost.context - available at git://git.gitorious.org/boost-dev/boost-dev.git
  (branch context-dev)

@Vicente: I've send you several emails without response - possibly your 
ISP filters my emails (SPAM)?

regards,
Oliver

- context:
   - stack unwinding:
       bool context::finished() const indicating that the called 
function has finished
       -> stack already unwinded
       void context::unwind_stack() jump back into context and throw a 
special exception
       -> stack will be unwinded (requires that no try/catch(...) was used)
   - context is now moveable
   - is not a template == the stack type is only passed/known in the 
templated ctor
   - the function to be called by the context is not saved on top of the 
stack
   - exceptions replaced by assertions / exceptions.hpp removed
   - fcontext_t used as default implementation; ucontext_t only fallback 
for platforms not supported by fcontext_t
   - on Windows Win Fiber API is used as default

- protected stack:
   - keyword explicit added to ctor
   - public static members min_stacksize, max_stacksize, default_stacksize

- fcontext_t renamed to boost_fcontext_t, boost_fcontext_get(), 
boost_fcontext_set(), boost_fcontext_jump(), boost_fcontext_make() -> 
move into global namespace

- i386 ASM preserves SSE2 control/status word

- x86 ASM uses indirect jump for boost_fcontext_set() and 
boost_fcontext_jump()
