The __forceinline was added in 1.49 at the request of some users, and it
has a measurable performance impact, so I'm inclined to keep it.

That's super-annoying. Have you filed a compiler bug? The MSVC team
isn't very responsive about fixing their bugs, but it has been known to
happen from time to time.

As a work-around, you can try compiling with /DBOOST_FORCEINLINE=inline.
The warning should go away, but your code might run marginally slower.

HTH,
