Please tell why do you need this.  Unless absolutely necessary, it is
not recommended to use backslashes in file names inside Makefiles; see
the file README.DOS in the Make distribution for the reasons and
explanations.

Escaping should work, in general.  But it doesn't work in every place
in a Makefile; that's one reason why it should be avoided.

That's because GCC produces file names with forward slashes.

Probably because GCC's -M feature does not support backslashes.

Again, please tell why do you need to see backslashes.  DOS doesn't
care, DJGPP programs don't care, so why should you care?
