---------------------------------------------------------+------------------
 In error_code.cpp, conditional macros choose the system call used to
 resolve error code values to strings (~line 81). The inline documentation
 mentions that strerror_r is used to provide thread-safety on platforms
 that expose that call.

 However, for Windows, the strerror call is always used, which is not
 thread-safe.

 Since VS2005, the Windows API has provided strerror_s, a thread-safe
 alternative to strerror that is similar to strerror_r.

 If possible, the strerror_s call should be used on Windows platforms that
 provide it.

 I am not an expert on the Boost way to select on Windows API versions
 internally so I hesitate to propose a patch but the form would be similar
 to that used for the strerror_r calls in that same area of the code.
