I did not understand this part. Who is "it"? gcc? I tried gcc -v -m64 -c t.c and I do not see -m32 anywhere...

For the time being, I built x86_64 cross compiler and then I built the 64-bit Linux kernel. It works (apart from some minor trouble with sound driver). Thanks guys for your software! -- vda
