By `dosify' do you mean converting the slashes to backslashes?  Then just 
use $(subst) built-in.  You might discover that the Win32 version of make 
already supports the backslashed pathnames, but I'd recommend to stay 
away from them as much as you can, because their support is incomplete 
(and cannot be made complete because it conflicts with some fundamental 
Make features such as filename wildcards etc).  IMHO, using ported GNU 
tools which support forward slashes is the best solution (and also will 
let you stay sane, especially if you work on Unix from time to time).

If you need the entire GNU toolchain (or large parts thereof), it might be
useful to try to enable LFN on NT from DJGPP library, because then you
just relink the available DJGPP ports and get a coherent toolset.  If the
LFN/NT project is too much for your resources, I'd recommend to compile
the DJGPP-patched sources with MSVC.  You will have to write a custom
replacements for some library functions, because the DJGPP ports rely on
the extended functionality of its libc to save some porting pains (a
notable example is `stat' and `fstat'), and I doubt that MSVC library has 
something to offer here, but you can just use the source of DJGPP libc.
