The documentation for GNU make (3.27) says that

          x: y.o z.o

     when `x.c', `y.c' and `z.c' all exist will execute:

          cc -c x.c -o x.o
          cc -c y.c -o y.o
          cc -c z.c -o z.o
          cc x.o y.o z.o -o x
          rm -f x.o
          rm -f y.o
          rm -f z.o

On this machine (Alliant FX/8), the compiler complains:

    cc: -o would overwrite x.o

Shouldn't the "-o x.o" be omitted if the -c flag is present?
