If they are .PRECIOUS, then an interrupt means that the file will not be
removed.  However, the patched rule creates the target file as the
output of $(YLWRAP).  If an interrupt came just after ylwrap finished,
then an incorrect .c file would be left, breaking future builds.

Yeah, oops.
I will fix it shortly.
