What are the values of RM and RMFLAGS?

The DEL (or ERASE) command that is provided by CMD.EXE is not as makefile
friendly as Unix's rm. I have a wrapper .bat file derived from the one
provided by WindRiver for their Tornado/VxWorks environment for NT:

vxrm.bat
---------------
@echo off
:start
if "%1"=="" goto end
if exist %1 erase /f /q %1 > nul
shift
goto start
:end
---------------

Now you can do this:

-----
RM = vxrm.bat # must be in your PATH

clean:
        $(RM) *.ilk *.vdb
-----

I guess this forces the RMFLAGS to be "/f /q", but I've never needed them
to be anything else, so it hasn't bothered me. Maybe you can change the
erase line in the batch file to:

if exist %1 erase %RMFLAGS% %1 > nul

But I have never tried this.
