I've ran into this too, with MSC 5.1.  It's a little annoying.  If you take
a look at the assembly file MSC generates, the first line in the externals
list is:

EXTRN  __acrtused :ABS

It isn't used in the rest of the listing either.  So it seems that you could
safely give the linker a bogus reference in your assembly code.  It works
for me.
