   4    These are compiled in a couple of different ways (always on a
   5    Darwin system):
   6    Basic compilation:
   7       for FILE in basic1.c basic2.c basic3.c; do
   8          clang -g -c $FILE -o ${FILE%.c}.macho.x86_64.o
   9       done
  10       clang basic1.macho.x86_64.o basic2.macho.x86_64.o basic3.macho.x86_64.o -o basic.macho.x86_64 -Wl,-dead_strip
  11
  12    LTO compilation:
  13       for FILE in basic1.c basic2.c basic3.c; do
  14          clang -g -c -flto $FILE -o ${FILE%.c}-lto.o
  15       done
  16       clang basic1-lto.o basic2-lto.o basic3-lto.o -o basic-lto.macho.x86_64 -Wl,-object_path_lto,$PWD/basic-lto.macho.x86_64.o -Wl,-dead_strip
  17       rm basic1-lto.o basic2-lto.o basic3-lto.o
  18
  19    Archive compilation (after basic compilation):
  20       ar -q libbasic.a basic2.macho.x86_64.o basic3.macho.x86_64.o
  21       clang basic1.macho.x86_64.o -lbasic -o basic-archive.macho.x86_64 -Wl,-dead_strip -L.
