Which help page?

You copied them wrongly.  You ought to read the Info
documentation -- `info make' -- but briefly, the basic syntax
is:

    target: dependencies
    <tab>command

You can have more than one command -- put them on separate
lines, in the order they should be executed.  They must be
indented using real tab characters.  Your makefile ends up
looking like this (but watch out for the tabs):

    CC=gcc
    CFLAGS = -c
    
    MkTest.exe : main.o serversocket.o
    
    main.o : main.cc 
    <tab>$(CC) $(CFLAGS) main.cc -o main.o
    
    serversocket.o : serversocket.cc
    <tab>$(CC) $(CFLAGS) -c  serversocket.cc -o serversocket.o

There are still some problems with it though.  I don't think
Make knows how to make the .exe like that -- you must tell it.
Also you could just lean on the built-in rules here and write a
much shorter makefile, but at first it's probably best to learn
one thing at a time.
