That won't work on a Unix box, when the package is built/tested in a
cross-compiled environment.

I think it might be possible to replace Sed commands with a suitable
GNU Make magic, using the built-in string-manipulation functions.
Failing that, we could add some simple string-replace code to
misc.exe, and use that as a portable alternative to Sed.

We couldn't find one, I think.  Mark?

Yes, that's what I would do.

Alternatively, you could compare the machine instructions generated by
your assembler with the machine instructions in the stock v2.03
library version of exceptn.S (you could use objdump for that).
