But it would fail to turn on optimization. So, better like:
CFLAGS="-m64 -O" CXXFLAGS="-m64 -O" ./configure

Regarding the __i386__ definition: There is code in m4/general.m4 that 
ought to correct the misleading uname -m output if kernelland is 64 bit 
and userland 32 bit. It's worked for others so far. Why does it fail for
