Thanks Philippe, the patch makes things look much nicer! Here's the output
(with wine specific output you don't care about removed):

the first (missing shlwapi), is valid, wine doesn't build .pdb files for its
own dlls. 
libmono-2.0-x86.pdb is also not included in wine-mono, not sure why it didn't
get one when others did, but that's how it is
the other two are C# dlls, so the unexpected pdb format makes sense

FYI, I've written a patch for this format for `file`, it's header is:
BSBJ\001\000\001\000\000\000\000\000\f\000\000\000PDB\ v1.0

though note that the 'v' is case insensitive.

As far as I'm concerned, this patch is good enough for now. I'll likely file a
follow up bug once this is resolved so that it's known/documented, but I don't
think the effort to implement is worth the gain, unless running c# code under
valgrind gets popular..
