Ah, I was wrong then.  The procedures were removed much more recently
than I initially thought.  The culprit is:

    2007-04-06  Robert Dewar  <dewar@adacore.com>
            Thomas Quinot  <quinot@adacore.com>
            Ed Schonberg  <schonberg@adacore.com>
            Bob Duff  <duff@adacore.com>
[...]
        * s-finimp.ads, s-finimp.adb (Move_Final_List): New procedure to move
        a return statement's finalization list to the caller's list, used for
        build-in-place functions with result type with controlled parts.
        Remove no longer used entities.
[...]

This is revision 123558 in Subversion.  The next version of GCC
without these procedures will be 4.3.0 (not released yet).

Since the procedures you need were removed because they were "unused",
it may be possible to reintroduce them into the compiler.  However the
risk is that they do not work with Ada 2005's interfaces.
