Vaclav,

Per library embedding for VC2005 is not worthwhile.  It's easy to do what I
need in Linux and OSX with <ldflags>.

So, I will add something like:

   if cfg._embed_libs:
        tool.setAttribute("UseLibraryDependencyInputs", bool2vcstr(True))

to the "VCLinkerTool" section generated inside msvs200xprj.py's
buildLinkerToolElement().

But what should trigger setting the bool?  My first impulse is to add a tag
(e.g <embedlibs/>), but maybe it is better to set a variable (e.g.
EMBED_LIBS) -- much like BUILDDIR or MSVS_PROJECT_FILE.

Which is more desireable, or is there a better way?

Thanks,
SB
