My PowerBook (also with Ubuntu Linux) sets it to "ppc", via uname -m, as per Make.unix. For MacOS X, $arch is appearently set to "power", so as a quick work-around to the assembly problems, I copied posix-power to posix-ppc and changed tas.c as attached. The only problem seems to be a slight disagreement in assembly syntax between MacOS and Linux. *shrug* Regards, Sven Moritz PS. In fact, the only thing different on Linux is that register names are not profixed with 'r', so, for example, instead of "li r0,0" on MacOS, it's just "li 0,0" on Linux... PPS. Do I hear the #ifdef's calling? *duck* No! No! No!
