I have seen variations on this problem on several platforms, a typical reason
is that the system's C library defines something as a macro, and then when the
libstd++ header tries to pull it in with

using ::somefunction;

the macro expands, causing mass confusion. It might be worthwhile to attempt to
run a compile with -E and look at the preprocessed output. It's an annoyingly
large amount of code but if something like a macro substituion is happening
inside that header, it will be fairly obvious.

No problem, just hope the fix what you're seeing on Windows isn't too hard to
find. :/
