[Qemu-devel] [PATCH] Support for DragonFly BSD

[Hasso Tepper <hasso@estpak.ee>]

[-- Attachment #1: Type: text/plain, Size: 482 bytes --]

The attached patch against trunk allows qemu to compile and work on 
DragonFly BSD platform (BSD usermode emulation targets disabled though). 
The patch is mostly straightforward, only few comments.

* Missing "monitor.h" include is a recent regression in trunk and with 
  this snippet removed the patch applies cleanly to the 0.10.0.

* Using /usr/bin/env should be generally a good idea. Most systems besides 
  Linux doesn't have perl in /usr/bin.


regards,
