In reviewing this patch, I see that there are some pieces that I forgot
to include. So the patch can not be accepted as is.
However, would you mind telling us what you think about the principle?
If you want my opinion, I am strongly attached to the idea of having
one subdirectory per testcase. The current approach used for C where
you can pretty much always have all the code for one testcase stored
in one .c file simply does not work for Ada. With GNAT, you need the
filename to match the name of the unit, and you need to have one and
only one unit per file. Most testcases will involve at least 3 files,
one containing the main procedure (that one compilation unit), plus
a .ads file containing the spec of a package, plus a .adb file
containing the body of a package. Some testcases will use many
more files than this (we have one testcase internally that creates
something like 200 packages).
For maintenance reasons, I really feel that one subdirectory per
testcase is the way to go.
I hope you'll agree with me, in which case I'll work on producing
a new iteration of this patch, complete this time.

: This rule can actually be worked around with GNAT, by using
gnatchop. What you do then is storing all the code in one file,
and then let gnatchop parse it and cut it into files that follow
the GNAT convention. I don't like this approach, though. One of
the problems is that it is suboptimal in terms of efficiency, since
you end up parsing the entire code to split it every time you run
the testcase. It's just better to have then already splitted. It's
also easier to track the changes in individual files rather than
one bigger file. And also, we might override during the split other
files created during previous testcase runs. Very annoying to have
the wrong code when you come back after en entire testsuite run and
try to understand why a given test failed.
