	-@rm \$(MINIPERL_EXE)

The "-" at the front of the recipe means that the exit code of rm is ignored.  (The @ means the command isn't echoed.)

From the GNU make documentation:

   To ignore errors in a recipe line, write a '-' at the beginning of
the line's text (after the initial tab).  The '-' is discarded before
the line is passed to the shell for execution.

   For example,

     clean:
             -rm -f *.o

This causes 'make' to continue even if 'rm' is unable to remove a file.
