[omniORB] solution for problems compiling projects using msdevstudio 6

[Andrew Stitcher]

[This info is a bit hazy in my head, but I think the guts are right]

By default when using the Microsoft compilation tool chain here is 
what happens:

If you specify an import library in the link line (even if you don't 
use any of the symbols from the corresponding dll) the executable 
that is generated is marked as using the dll. For normal (debugging) 
builds I don't think you can avoid this, if you don't want a dll 
don't include the import library.

If you specify the "Minimize Size" optimisation, this enables 
function level linking. This causes the linker to notice which 
functions are being used or not and not to link in the ones that 
aren't. As a side effect the linker will notice if any of the 
specified dlls aren't actually being used, print a warning message 
and take it out of the executable.

Incidently, the "Minimise size" optimisation is recomended for 
release builds over the speed optimising setting.
