Maybe Emacs could be changed after the release so that local variables
will work. AFAIK previous Emacsen didn't use the overlay arrow in the
compilation buffer. My concern is that these changes have broken something
in GUD.

FWIW I could not reproduce Juan-Leon's error. In fact if I set
next-error-highlight to 'fringe-arrow I could only get one arrow to display
(in the compilation buffer). The source buffer showed nothing. This is what
I would expect, however, because the same thing happened in gdb-ui when
both the source buffer and assembler buffer until you made the changes which
allowed multiple overlay arrows. With Gnus and GUD, don't they constantly
steal the arrow from each other?

Juan-Leon can you see an arrow in the compilation buffer and source buffer
at the same time?

I am guessing that the change I proposed would fix the error but as I am
not familiar with the underlying C code, I might just be replacing one
kludge with a better one.
