Are there any cases where you had to do something other than just regenerate the various files?
Nope - at least nothing that I would call "doing something other". What I did:
* touch each configure.ac to ensure automake is really used
* do 'make bootstrap' with one single job (updating scripts while running them is bad)
* once-off add "testsuite/other-tests/Makefile" to AC_CONFIG_FILES in libvtv/configure.ac,
as that is unused but shows up in the "by automake 1.11.x" search
If not, then as long as you fix the ChangeLog entries per Jakub's comments and ensure that you've also tested Ada, then this can be installed into the trunk.
Sure, and two more:
* Sort out whether to update those top-level "missing" scripts.
