Mechanisms that have been replaced with something better, simpler,
cleaner; or are no longer required by core-GDB.  New code should not
use deprecated mechanisms.  Existing code, when touched, should be
updated to use non-deprecated mechanisms.  See obsolete and deprecate.
(The declaration and definition are hopefully excluded from count so
zero should indicate no remaining uses).
EOF

Mechanisms that have been replaced, but have not yet been marked as
such (using the deprecated_ prefix).  See deprecate and deprecated.
EOF

    print_toc 0 -1 deprecate Deprecate <<EOF
Mechanisms that are a candidate for being made obsolete.  Once core
GDB no longer depends on these mechanisms and/or there is a
replacement available, these mechanims can be deprecated (adding the
deprecated prefix) obsoleted (put into category obsolete) or deleted.
See obsolete and deprecated.

Methods used to prop up targets using targets that still depend on
deprecated mechanisms. (The method's declaration and definition are
hopefully excluded from count).

Count of calls to the gdbarch set methods.  (Declaration and
definition hopefully excluded from count).
