[Per Bothner]

Ok to check in?

        * dwarf2.h:  Partial merge with gcc version.
        (enum dwarf_descrim_list):  Fix typo -> dwarf_discrim_list.
        (DW_LANG_Java):  Use value from dwarf 2.1 draft (also used in gcc).

Shouldn't the copyright years include 2001 as well?

Well, the gcc/dwarf2.h doesn't, and this is basically a merge
from that.  (There are some formatting differences, and there
are also some extensions in the binutils version.  I'm leaving those
as is for now.)

Ok, you haven't changed anything. But still, the file itself has been
touched. Hmm, I don't know what the rules are in this case.

Anyone?

The rules are that the Copyright notice should mention years when
someone worked on a released version of a file.  So if the changes
were done by GCC maintainers only in 2000, I think it is okay not to
include 2001.

Thanks for clarifying this, Eli.
I withdraw my objection.

Hmm, include/.... Didn't notice that detail.

As the file notes:

	This file is part of GNU CC.

Since GCC has the master, people are free to just import the latest 
changes at their leasure.  Just remember to warn GDB and (if relevant) 
binutils when it is happening (perhaphs with a sanity build :-).
