Re: new compile command doesn't coalesce errors on the same line

[Daniel Pfeiffer]

Hi Miles,

I'm not sure a compiler with buggy messages should force the default value for
compilation-skip-visited.  But gcc is probably the most frequently used
program inside compile, so I'd already accepted what looks like the majority
verdict, of making this option be t.  For those who would like to set it to
nil, here's an example of four messages pertaining to one line, and only two
are directly related:

$ perl -we '$x = foo; print "$y\n"'
Unquoted string "foo" may clash with future reserved word at -e line 1.
Name "main::y" used only once: possible typo at -e line 1.
Name "main::x" used only once: possible typo at -e line 1.
Use of uninitialized value in concatenation (.) or string at -e line 1.

And those are?  I asked some clear questions.  What is it you want that my
option can not give you?  And how do you want to handle the example I gave
(recognizing multiple locations on a line), which you didn't answer?

Geez, you've got your very constructive day again!  The old one was awful, not
differentiating an error from a warning or info, clueless about multiple
locations on a line, randomly pretending there's no error on the current line
even though it's highlighted or sometimes even going to a wrong file...
