What I'm suggesting is to replace the last command ("mv $@-t $@") with this: move-if-change $@-t $@ That's it. Make will indeed cheerfully regenerate unistd.h-t
... and alloca.h-t. And getopt.h-t. And the other ten .h-t files that are generated on typical platforms. And this would occur every time one does a 'make', even when there's no real work to do. The unnecessary "make" actions would fill up people's screens, and would be confusing. I'm afraid this cure would be worse than the disease.
