Christopher Faylor 77f4a25028 * Makefile.in: Autogenerate some header files which provide magic numbers.
Force dependencies for files which depend on autogenerated headers to ensure
that they are always built.
* child_info.h (child_info): Add new fields to accommodate new magic number
header stuff.

magic numbers are used.
