It works fine for me (on Linux-- I don't have a Windows box):

  $ cat Makefile
        echo '$(DSPTOOLS)\cl500 $(COPT) -fr $(OBJDIR) -cg -i$(INCDIR) $<'

        echo '$(DSPTOOLS)\asm500 $(AOPT) -v548 -i$(INCDIR) $< $(OBJDIR)/$(@F)'

  $ touch foo.asm

  $ make
  echo '\asm500  -v548 -i foo.asm /foo.obj'
  \asm500  -v548 -i foo.asm /foo.obj

  av> Any idea why?

Please provide full information: an exact makefile, exact steps to
reproduce from an empty directory using simple tools, the version of GNU
make you're using (make --version), how it's compiled, etc.
