Part of any effort here would also include taking the Travis and Appveyor
CI files from boost::uuid and run all the checks in boost::random therefore
any incompatibilities such as the one expressed for MinGW would be
identified.  In fact, it would make sense to add some additional unit test
files and/or builds to Appveyor to check different _WIN32_WINNT
compatibility levels to ensure all the build-time code branches are covered
(as well as WINAPI_FAMILY differences).  The documentation on rand_s
doesn't lead me to believe it is compatible with all platforms, as it
expressly states it depends on an API that only works on Windows Desktop
applications, however a well formed CI environment would prove it out if
rand_s was to be used.
