It purportedly converts MASM (which uses an Intel-style syntax) to the AT&T style. It might just work, though more likely we'd have to tweak it to understand various idiosyncrasies of ASASM.

I'd been thinking of tackling it with OMeta/JS if I didn't find anything else to use, but then I saw this:

Interesting. Another possibility we've been discussing would add the source for asasm to the squeak SVN tree and add rules to make it at need. It's GPL licensed, which might or might not be a problem; I'm sure somebody will have opinions. 

On a related issue, I finally made enough sense of cmake to spot a way to get the relevant define, err, defined, without having to alter the sqPlatformSpecific.h, which is a nice improvement. I'm still inclined to think that some manner must exist to only try to compile the related C files if you want them, rather than relying on the library linking to dump unwanted code.
