It's written in linux Next ,all The target file of is an executable file by default. You can check the update of the file dependency , But somehow Windows I can't , Write like this

all:message.exe ClientMessage.exe
message.exe:messageDeal.o   
 gcc messageDeal.o -o message -lpthreadlWs2_32
ClientMessage.exe:ClientMessage.o    
 gcc $< -o [email protected]
%.o:%.c
