Re: [RFC PATCH] Deprecate _REENTRANT and _THREAD_SAFE.

For many years, the only effect of these macros has been to make
unistd.h declare getlogin_r.  _POSIX_C_SOURCE >= 199506L also causes
this function to be declared.  However, people who don't carefully
read all the headers might be confused into thinking they need to
define _REENTRANT for any threaded code (as was indeed the case a long
time ago).

You should get rid of the internal #define and #undef of _REENTRANT, too.

Thanks,
