I'd make that be more like:
realclean :
@chflags -R 0 ${.OBJDIR}/*
@rm -Rf ${.OBJDIR}/*
since sometimes you wind up files that have flags set on them. I once
looked into hacking rm to do that in one step, but couldn't figure out
a way to do it race free and punted. There was no notion of a
funlink. this is conceptually as close as I got:
fd = open(path, O_RDRW); /*1*/
fchflags(fd, 0);
unlink(path); /*2*/
which races between /*1*/ and /*2*/.
If you can tolerate errors in the output, the following is faster
because the chflags has lots less work to do:
realclean :
@rm -Rf ${.OBJDIR}/*
@chflags -R 0 ${.OBJDIR}/*
@rm -Rf ${.OBJDIR}/*
