Attached you'll find a (big) patch that fixes make dep and make
depend in all Makefiles where I found it to be appropriate.

It also removes the dependency in Makefile.global for NAMEDATALEN
and OIDNAMELEN by making backend/catalog/genbki.sh and bin/initdb/initdb.sh
a little smarter.

This no longer requires initdb.sh that is turned into initdb with
a sed script when installing Postgres, hence initdb.sh should be
renamed to initdb (after the patch has been applied :-) )

This patch is against the 6.3 sources, as it took a while to
complete.

Please review and apply,

Cheers,
