This might be overkill, so if it is, just ignore me or something ...

I've attached some log excerpts for everyone's enjoyment.  All the dwarf-2
logs look like the first one (gcc 2.95.3, gcc 2.96-rh, gcc 3.0.4,
gcc gcc-3_1-branch%20020505, gcc HEAD%20020505).  All the stabs+ logs look like
the second one (same batch of gcc compilers).

It's definitely a dwarf-2 versus stabs+ issue with argument types in
pointer-to-function, not a v2 versus v3 "void" representation thing.
Look at the _struct_decl declaration.

(The hard part about the test suite is mining half a million test results
and putting it in a form where people can see a pattern).
