James, 

Even with delays caused by a new job I should have the port of GCC
done well before then.

However, if unforseen circumstances arise... the GCC HC12 output
wouldn't be difficult to port.  It would mostly be search and replace
of instructions dealing with loads and stores.

The real problem you'll have is that the author of the HC12 port
didn't seem to spend a lot of time optimizing to code output and it
uses a lot of software registers.  That might be ok for an application
but it's not such a good idea for a driver to take up most of page 0
or the DP page.
