Na..This is not for kernel building. It for ia64 developemnt (C 
programs).

 CFLAGS="-O2 -Dinhibit_libc" ../gcc-3.2/configure 
--target=ia64-unknown-linux --prefix=/FPS/Bunny/work/ia64.bak/ 
--enable-languages=c --disable-shared --disable-multilib 
--enable-threads=single --with-headers=/FPS/Bunny/work/nue/include 

I have copied /nue/usr/include and given that headers.make reports the 
following error.

Please note that i have not include --with-libs . Hope this libs are 
fine.Also i have 2.3.

Exactly / The build procedure should work for any target system.
Also in the previous case i didn't have to copy the header files.Maybe 
they are compatible with the standard  header files and this one is not.
