Maybe you can have an intermediate file created from config.status
(AC_CONFIG_FILES), and then use move-if-change to the header, in
conjunction with a stamp file.  I'm not sure whether there are make
implementations that don't cope well with this scheme, nor whether
that is due to bugs in them.

Cheers,
