  * Added tests/user001.hs which tests all the get* functions in System.Posix.User.
  I added this since I noticed that getUserEntryForID, getUserEntryForName,
  getGroupEntryForID and getGroupEntryForName failed on OS X 10.4.9 on i386.

    M ./tests/all.T +1
    A ./tests/user001.hs
    A ./tests/user001.stdout
