This reverts commit c27b645956.
This commit has been reverted because the new mechanism was too
sensitive to changes in the lisp source, generation of new ldefs-boot
files was platform specific and resulted in warnings about undefined
variables.

# Dependencies
|
|
|
|
## None of the following matters for bootstrap, which is the only way
|
|
## to ensure a correct compilation of all lisp files.
|
|
## Manually specifying dependencies of a handful of lisp files, (and
|
|
## ones that don't change very often at that) seems pretty pointless
|
|
## to me.
|
|
|

# http://debbugs.gnu.org/1004
|
|
# CC Mode uses a compile time macro system which causes a compile time
|
|
# dependency in cc-*.elc files on the macros in other cc-*.el and the
|
|
# version string in cc-defs.el.
