  FreeBSD src repository

  Modified files:
    usr.bin/ar           write.c 
  Log:
  Handle properly when insert zero size objects into the archive:
  Do not mmap 0-size objects and do not try to extract symbol from
  0-size objects, but do treat 0-size objects as qualified objects and
  accept them as an archive member. (A member with only the header part)
  
  Note that GNU binutils ar on FreeBSD ignores 0-size objects, but on
  Linux it accepts them. [1] But, since this is a rare usage, we can
  safely ignore the compatibility issue.
