sudo 1.6.4 release candidate 3 now available

[Todd C. Miller]

We're still on schedule for a 1.6.4-final release on Monday.

The following changes have been made since 1.6.4rc2:

 o Fixed a compilation problem on AIX which for some reason appears
   to not be prototyping malloc().  Explicit casts are now used to
   pacify the AIX compiler.

 o install-sh behaved badly if neither whoami nor id were found.

You may download the tarball from:
    ftp://ftp.sudo.ws/pub/sudo/beta/sudo-1.6.4rc3.tar.gz
