  SVN rev 207599 on 2010-05-04 05:34:18Z by kib
  
  MFC r206893:
  Slightly modernize realpath(3).
  
  SUSv4 requires that implementation returns EINVAL if supplied path is NULL,
  and ENOENT if path is empty string [1].
  Bring prototype in conformance with SUSv4, adding restrict keywords.
  Allow the resolved path buffer pointer be NULL, in which case realpath(3)
  allocates storage with malloc().
  
  MFC r206898:
  Free() is not allowed to modify errno, remove safety brackets around it.
  Add small optimization, do not copy a string to the buffer that is
  to be freed immediately after.
  
  MFC r206997:
  Move realpath(3) prototype to a POSIX section.
  
  MFC r206998:
  Add standards section, improve wording, taking into account the handling
  of NULL and changed type in declaration.
