I have several libs compiled in vs2010 that I need to convert

With the same setup I have this linked in win64, just want to
get win32.
I have tried coff2omf but it fails with:

This lib does require some boost libs I have compiled, these
libs do end
with vc100-mt-1_56.lib. The look like
libboost_chrono-vc100-mt-1_.56.lib
So maybe the dash messing up coff2omf.
the digitalmars site says you need to convert the coff format
via link /
lib /convert [lib]. Is this only for really old version of vs?
link /lib /convert leveldb.lib

objconv seems to work on the boost lib files but not leveldb.lib
I tired messing tring to get dmc to compile boost, but there
are tons of
errors, to many to make me want to not go that path.
So does anyone have a fool prof way of converting coff to omf
libs. I
feel like this use to be easy..
Thanks,

You can also look at http://www.agner.org/optimize/#objconv.
I used it quite a long time ago to convert OMF libs to COFF (the
opposite of what you need), and only for Win32.
But it looks reasonably up-to-date and it claims to support both
Win32/Win64.
