Since the latest GAS distribution does not support the '040, obviously I will not be installing or using GAS. You might want to try it, anyhow. The '040 really isn't all that different from the '030 - for instance, not so different as an '030 compared to an '020 or an '020 compared to 68000/10/8. Unless you're using floating point (which I very much doubt a crt0.c file would use :-), there would probably be no problems at all with using gas, at least for a couple files. Then again, don't be so sure that /bin/as isn't gas. Though I can't check without an OD-capable system at hand, I believe that NeXT distributed as source with the other GNU source in 1.0. Thus, I would tend to believe that as is gas by another name. Try it! The main problems (of course) with using a non-NeXT gas center around generating the right .o format . . . important, if you wish to link with anything that's put out by NeXT, or don't want to have to atom everything you create, or don't want to have to port the gnu loader, too.

I thought the '040 was backwards compatible with the '030; ie., any '030 binary would work on the '040.

Thus, I >would tend to believe that as is gas by another name. Try it! My hunch is that /bin/as on the next is GAS 1.28, modified by next. Try: localhost% strings /bin/as | grep as For those of you without the spirit to try it for yourself, here's the last few lines of the output. Note that the assembler knows about obj-c, and I'd bet GAS straight off prep.ai.mit.edu doesn't. objc_class objc_meta_class objc_class_vars Bignum assumed to be binary bit-pattern Internal Error: Can't hash %s: %s Gnu assembler version 1.28 (I guess.)
