No, for that:

https://github.com/boostorg/system/blob/master/include/boost/system/detail/error_code.ipp#L24

Or, in general, we use separate compilation to isolate the users of the 
library from the header dependencies required to build (but not use) the 
library.

In this case, after the recent fixes, maybe.
