Advice needed: programmatically generating primops?

[Geoffrey Mainland]

That was what I wanted to do at first, but I don't think it's possible.

First of all, on Linux at least, we invoke the preprocessor with
-traditional, so concatenation is not available. That could be changed.

Without -traditional, CPP doesn't like the # characters in the names of
our primops. If you see how to get around that issue, please let me know
:)
