Can you tell us what change can be made to the code to effect what had been gained by using that macro?
It's unconditionally:
#define _FPOSOFF(fp) ((long long)(fp))
So you should be able to replace it with a static_cast, or eliminate it entirely.
That might break older versions, or other uses of Dinkumware.

I don't have access to Visual C++ so I can't do it myself. If anyone wants to, all the relevant code is here: https://github.com/boostorg/iostreams/blob/develop/include/boost/iostreams/p...
