The make provided by MSYS is a copy of some version of source from Cygwin.
 There are local modifications that are not present in the official
source.  It also uses the unix source path instead of the Win32 source
path.

You mean a runtime environment variable?  Nothing that I would use as a
portable method.  The shell bit would need to be set at runtime.  Besides,
I  could have fileutils installed without a shell and use rm -f for RM
anyway.  You should be sure to check the predefined variables such as RM,
CC, etc and set those appropriately based on the runtime environment then
use the variable in the command.

<example>
clean:
        $(RM) *.obj
</example>
