You're welcome.

Apparently I have since fixed that.

Ok.

Hmm. build/Makefile inherits GNAT_VERSION from the environment, with no
default. I set that manually in my ~/.emacs, depending on which version
I'm working with.

We should be able to compute it from 'gnat --version'.

In addition, I just realized the instructions in ada-mode.info fail for
building gpr_query in ~/.emacs.d/elpa; they don't create gpr_query.gpr.
And the info menu structure is wrong.

>From reading the gnat user guide, it appears gprbuild cannot run
gnatprep to create a .gpr file, at least not without providing a
gprbuild xml file to teach it how. So I need a script of some sort.

POSIX shell seems a good choice; Linux and Mac have it, and Windows
users can get it via Cygwin or MSYS. That can also compute the gnat
version from `gnat --version`. 

On the other hand, gprbuild xml files are not that hard to figure out,
and can extract strings from command results. So I'll try that first.

All this means I need another release. I should have bumped the second
digit; this release should have been 5.3.0, So the next will be 5.3.1.

And the next will (hopefully) be 6.0.0, with a new indentation engine
(Now Improved!) and error recovery in the parser.
