Revised test case, with suggested revisions.
Paul N. Hilfinger
(Hilfinger@adacore.com)
This test stops inside a recursive function after a few levels of recursion,
goes up some frames, and then accesses a local variable with 'print foo::val'
rather than the usual 'print val' to see if the former pays attention to the
selected frame.

In the ChangeLog file, I would merge these two entries. I think
that the ChangeLog is meant to track the changes in the repository,
and does not need to track the iterations that the patch went through
during review...

Thanks! I updated the testing cookbook to include the ones I could
find there, as well as in gdb.exp. That's 7 variables in total,
including one I forgot about (octal).

I don't have a strong preference.
I mostly just wanted to raise the issue.
The patch is fine with me.
[I'd feel uncomfortable with forcing someone to hack on scope* before
cleaning it up anyway. :-)]

Joel,
These are part of dejagnu, defined in .../share/dejagnu/runtest.exp on my
Ubuntu installation, along with a bunch of definitions of
configuration/environment parameters.

Do you know where these are defined? And are there any other such
useful globals that we can use? I need to document them in the
testing cookbook, because I keep looking for them, and then
eventually redefine them over and over again...
Thanks!

Personally, I think it's fine to have a small self-contained
testcase that deals mostly with scoping vs recursion. I actually
like it better that way, but I know people may prefer it the other
way. My opinion for liking smaller testcases is that it's usually
easier to reproduce the problem: You don't have to sort through
a lot of unrelated stuff that happens before the problem occurs.

I defer to whatever consensus develops. All the tests in scope.c that use "::"
stick to static variables, whereas the new test uses :: in an admittedly
undocumented fashion and concerns dynamic, rather than static, scoping. However,
I don't know what criteria there are for grouping tests.
Thanks for your comments.

This test (from Joel Brobecker) stops inside a recursive function
after a few levels of recursion, goes up some frames, and then
accesses a local variable with 'print foo::val' rather than the usual
'print val' to see if the former pays attention to the selected frame.
