New Revision: 203868
URL: http://svn.freebsd.org/changeset/base/203868
Log:
Some cleanups from NetBSD:
- C99 initializers.
- Change the default volume label from "NO NAME" to "NO_NAME".
- Set OEM String to "BSD4.4 " following the unnamed spacing convention
in that other OS that suggests "MSWIN4.1"
Also, David Naylor's changes for Clang, mostly changing the signess
of constants.
