It only tells us that uname(2) gives useless information on the platform, but there are other ways to ask the system for more useful information. Isn't that the same deal with how useful information is obtained from not uname(2), since a useful one does not exist there, but from GetVersion() on mingw? We do not have to spawn an external process on MinGW to do this---we shouldn't have to do so on NonStop, either. We should be able to make a call into a NonStop specific code you or Randal add in compat/ from get_uname_info() to hide the platform-specific details, no?
