I'm talking about the comment 2 by Brad:

Walter expressed he agree with this comment in comment 3.

AFAIK this pull request works for -g instead of -gc, even when it uses standard
DWARF features, which goes against that comment.

In the bug 3389 that you just closed, Robert Clipsham makes what for me is a
good point:

At least this will be more familiar with people used to GCC command line
arguments (which is probably 100% of the *nix world), where -g is the default
for debug and you have, for example -ggdb for GDB extensions.

AFAIK there is no clear direction about this. But maybe is a topic for another
bug report, I think I'll reopen bug 3389 because the root issue in that bug is
what's being discussed here.
