Hello, I'm the responsible of the Linux packages building process (http://dlang.org/download.html) and I'm absolutely disagree with you.
- Linux can compile to 64-bit since may 2011, Windows just now. - Linux has 32-bit and 64-bit binaries since may 2011, Windows 32-bit only. - Last dmd release includes "libphobos2.so" Linux shared library. Will see when "phobos.dll" will be available for Windows. Regards, -- Jordi Sayol
