illumos gate

The POSIX 2008 standard documents struct timespec with members tv_sec and tv_nsec. However, if standards are requested, these become __tv_sec and __tv_nsec on illumos derviates. There are comments in the relevant headers referring to the latter names as "standards namespace safe versions of these definitions"[1], but that doesn't make sense, as those member names don't comply with a defined standard. I realize that was done some time ago (2004 or earlier), and I understand that there may be legacy concerns that led to that approach originally being taken.
