Hi Akim,
Thanks for the patches!

This is an improvement, but for the fact that then all explicit
uses of warn would emit "$ME: $ME: ...".
What do you think about removing the "$ME: " prefix from
each existing warn argument string?

This looks fine, but I'd like mention in the log which system
required the change.  OS/X?

Here's a proposed log message:

    announce-gen: du -h is more portable than du --human

    * build-aux/announce-gen (sizes): Invoke du with -h instead
    of --human.  Accept leading white space in its output.
    These changes are required to accommodate ????'s du.
