I'm surprised.  See INSTALL if you don't understand the Emacs build
process.  It's normal, I think, and actually required for some
packages, even if you're not building for multiple targets at the same

Using `doc-directory' instead of `data-directory' is simply a bug.  I
don't understand refusing to fix things like that.

The arrow does no harm when it can be displayed.  The behaviour I'm
used to is putting the error at the top of the window.  (I'm also used
to tty mode for various reasons.)

But I don't, which is a reason to allow it to be customized unless I'm
quite unusual.

I don't understand what that has to do with compilation-minor-mode for
inferior REPLs.  I certainly don't understand anything about running
Ada like that, and I'm surprised it's possible.  I don't know what to
make of those compilation.txt examples anyway, actually.

I'm not, but the doc seems to be saying I should.

You must have some idea what it means which can be written down, or
the concept is quite useless and should be avoided.  You obviously do
give semantics to regexps in the regexp alist, and those are even
fuzzy, as in the case of `file' fields which don't correspond to files
but to streams.  Previously you implied that informational wasn't
meant to cover compiler messages.  If it does apply simply to compiler
messages, then distinction between warn and info doesn't appear to be
helpful, per my example.  It definitely isn't helpful if no-one knows
what the distinction is meant to be.

So much for dismissing my comment about developers' opinions...
