Hi,
I am the package maintainer for dosbox at fedora extras. As FC4 is right around the corner I wanted to get dosbox build on all supported archs (i386,ppc,x86_64). While the first two did not pose any problems x86_64 was a little bit more trouble. Attached is my patch against 0.63 release. Maybe some of the changes can in some or another way be integrated into the next version. The will compile fine on i386 and ppc two.

😀
