The problem is that values of variables from command line has higher
precedence over assignment within Makefile itself (the "override"
directive is an exception).  The configure step run prior to compile
correctly set WITH_POSIX macro with CPPFLAGS within the generated
Makefile.  But the way Build/Compile was defined preciously will
override the CPPFLAGS with a value without the -DWITH_POSIX.
