I prefer DOSEmu over DOSBox (mostly since I don't have to do crazy mounts and updates every time I change a file, and DOSEmu integrates better into the UNIX environment). I've used it for porting programs back to DOS on x86. However, it would be cool if I could build it on PowerPC with full x86 emulation (since there is no x86 CPU here) so that I could still use it rather than DOSBox.
configure: Compiling with optional 386 emulation code...
Your system has no complete code16 functional gas,
you must upgrade to atleast binutils-18.104.22.168.25
in order to compile DOSEMU ... giving up
