For above example I am using binutils-20001103, ld-20001204,
libbfd-20001204 from your distros  and static libiberty from
binutils-20001212 (my build).  

I still cannot get "lastest" ld-20001217 from your distro to work
(access violation in libbfd-2.10.91.dll). The diff file for ld-20001217
is identical to diff file for ld-20001204 and no debugging info in
binary so haven't been able to find source of access violation.  

The "latest" binutils-20001225.zip at SourceForge is an empty file.

Can you suggest anything to help me track down my problem.

Cheers

Danny
