defining knobs in pkgtools.conf question

[Chiang Seng Chang]

Hi,

This is from the lang/python Makefile

=== quote ===

OPTIONS=        THREADS "Enable thread support" on \
                 HUGE_STACK_SIZE "Use a larger thread stack" off \
                 UCS2 "Use UCS2 instead of UCS4 for unicode support" off \
                 PYMALLOC "Uses python's internal malloc" on

.include <bsd.port.pre.mk>

.if defined(WITH_THREADS)
CONFIGURE_ARGS+=        --with-threads
CFLAGS+=                ${PTHREAD_CFLAGS}
.if defined(WITHOUT_HUGE_STACK_SIZE)
CFLAGS+=                -DTHREAD_STACK_SIZE=0x20000
.else
CFLAGS+=                -DTHREAD_STACK_SIZE=0x100000
.endif # defined(WITHOUT_HUGE_STACK_SIZE)
CONFIGURE_ENV+=         LDFLAGS="${PTHREAD_LIBS} ${LDFLAGS}"
.else
CONFIGURE_ARGS+=        --without-threads
.if defined(LDFLAGS)
CONFIGURE_ENV+=         LDFLAGS="${LDFLAGS}"
.endif # defined(LDFLAGS)
.endif # defined(WITH_THREADS)

.if defined(WITHOUT_UCS2)
CONFIGURE_ARGS+=        --enable-unicode=ucs4
.endif

.if defined(WITHOUT_PYMALLOC)
CONFIGURE_ARGS+=        --without-pymalloc
.endif

=== end quote ===

So if I wish to put the knobs into pkgtools.conf so that it can build it 
batch mode, do I:

     WITH_THREADS=1
     WITHOUT_HUGE_STACK_SIZE=1
     WITH_UCS2=1
     WITH_PYMALLOC=1

or

     WITH_THREADS=1
     WITHOUT_HUGE_STACK_SIZE=1
     WITHOUT_UCS2=0
     WITHOUT_PYMALLOC=0

I guess my question is how to decide wheather to use WITH_XXX=1 or 
WITHOUT_XXX=0 ?

does WITH_XXX=0 result in #defined(WITH_XXX) returning false ?

Regards.
