Normally, you need to use the "section" construct to create a separate 
scope where a part of the compilation environment is redefined:

section
    OCAMLFINDFLAGS += -syntax camlp4o
    # tie specific targets to this section
    c.cmx c$(EXT_OBJ):
    c.cmo:
    c.cmi:

Note that the values of the variables (like the OCAMLFINDFLAGS) do not 
propagate outside from the indentation blocks (like the section block 
above), unless you specifically request it. So in the above code, the 
value of the OCAMLFINDFLAGS variable is automatically restored to the 
original value (without camlp4) once the "section" ends.

For more information, see the "Scoping, sections" section of the 
documentation -
