I'm pretty sure I've got the -L+ part right because when I didn't 
I got about 20 Symbol Undefined errors and if I leave out the -I 
part it doesn't even compile.

What's the trick to get the link to work?

Looks like that's a Windows API function [0].
Get it to link with OleAut32 and it should work, if I'm correct.

Thanks, Rikki
There was a pragma(lib,"oleaut32.lib") in one of the source 
files, so it should have been linking.
The problem now is that the DM oleaut32.lib doesn't include a 
_VarCmp 16.
I ran lib -l oleaut32.lib to get a list file.  No exported 
_VarCmp 16.  There were 400-odd lines of exports so I believe lib 
-l worked.
If I run implib /s oleaut32.lib oleaut32.dll vs. a windows XP 
oleaut32.dll I get an oleaut32.lib that includes a _VarCmp (not 
_VarCmp 16).
What's the secret sauce to creating an oleaut32.lib that's fully 
decorated?  Is there a way to get a newer oleaut32.lib into the d 
distributions.  The full dmc oleaut32.lib is also missing 
_VarCmp 16 so no joy there either.

I don't know enough about implib to explain it.
But another method that I believe should work is to use linker 
definition files.
It'll allow optlink to work.
Just add it to dmd, actually I believe it needs to be passed to Optlink 
(so -L it).

Another fix, might be to use 64bit, but shouldn't be required.

Rikki,
Thank you for your kind attention.  I spewed to the newsgroup and 
googled for an answer in the wrong order.  It appears the 
solution to this problem is the combination of coffimplib + 
windows SDK.  After using those on the SDK's oleaut32.lib I got a 
library with the properly decorated _VarCmp 16.

Not your job, but this could probably be made simpler.

You may want to spearhead the effort to get Win32 support of MSVC 
into D, if you care enough about it.  Rainer has done most of the 
work, you'd just have to turn his patches into pull requests, 
shepherd them through the review process, and maybe add some 
polish:

Let me see what I can do for time.  There's the above, it's also 
possible to link mixed coff and omf with jwlink 
(http://www.japheth.de/JWlink/JWlink.htm).
There's a couple of paths and while win32 isn't leading edge, I 
think enhancing it is a worthwhile project for lesser lights like 
myself.

I've tried the above and get a horde of errors.  Some seem to be 
weak link __symbol doesn't match the library's _symbol (two 
leading underbars on one side, one on the other).  Some seem to 
be some utterly missing capitalized symbols like GETLONG, 
GETPOINTER and STRLEN2.  The underbar mismatches I should be able 
to fix with a def file or maybe there's a (j)wlink option I 
missed to resolve those.
As I make progress, such as it is, I'll report.  Anybody who sees 
something I've missed feel free to chime in. While I'm learning I 
have no pride, I save it for pride in having learned.

I'd love to, but that might be a little over my head.  I see he 
forked from 2.060 and now we're almost in 2.066.  I'd have to 
radically improve my git fu and my D fu to be able to bring the 
patches up to 2.066.
I'm on some extended time off in a couple of weeks for some 
surgery, this might be a project to while away the recovery days.
