I cannot find anything about it in standards.texi (and the 14 feb one
from binutils 2.13 is the most recent one I have).
Emacs looked more promising (the ChangeLog mentioned a commit by RMS
that looked like your patch) and it did indeed have regexps for all
sorts of ranges, using dots (even though that goes against what GCC
uses); it just didn't work when I tried it.

BUT the regexps were broken (they considered the filename to include the
':' after it)!  I've just submitted a patch to emacs.
