Why the --disable-ipv6 option does not work?

[won seok]

Dear Edvard.

In fact, I have to port the Bind9 to mips board. 
The Bind9 is compiled very well when I used gcc. 
But there happened to appear errors about ipv6 when I tried to compile
it using mips cross compiler.
So I thought that the configure file of bind9 should be changed to
ignore ipv6 functionality of my development pc.

If you can give more advice to me, please read the following current
status.
1) ./configure --with-openssl=/root/openssl-0.9.7d  
        <--- the openssl is compiled by cross compiler. 
2) gmake CC=... mipsel-uclibc-gcc 
        <--- cross compiling
    ..........
    ./gen: cannot execute binary file. 
        <--- now the gen file is built with cross comipler so it can't
run on x86 machine. so returns error.
3) gmake 
4) copy files which are generated by gen utility to proper locations.
( code.h rdatastruct.h enumclass.h enumtype.h )
5) repeat the above 2)
     ..........
     error  about ipv6
6) modify the Makefile (bind9) 
     <--- I commented all ipv6 check lines. ( more 300 lines ) 
7) gmake CC=... mipsel-uclibc-gcc
    ............
    gmake[4]: exit `/root/bind-9.3.0beta4/lib/isc/unix/include'
