[Qemu-devel] [PATCH] Building on ARM host

[Qemu-devel] [PATCH] Building on ARM host

[Steve Magoun]

This patch cleans up some bitrot that prevented qemu from building on 
arm. It includes a fix for dyngen.h suggested by Chih-Chung Chang. The 
resulting binary runs simple i386 programs like 'ls' on an arm host.
