Re: Building GCC 4.9 biarch (i686+x86_64) on Debian 6.0 i686

I can live with 64-bit system, which has 64-bit GCC. What is essential for 
me is that I can build both 32-bit and 64-bit targets and then run 32-bit 
targets (during test phase of the build).

How difficult (easy?) is it to have 64-bit Debian/Redhat machine running 
32-bit executables?

Thanks
Alex
