I have implemented what Mark Riley has suggested. I submitted a patch
to the patches section at the sourceforge project page. The changes
are quite small but require some tricky tweaks to the build process.
I have only minimally tested it and only under linux, so if it breaks
for cygwin users let me know.
The patch currently puts the memory functions in high memory, but this
is easy to change. Just add __TEXT_HI__ to the definition of those
functions you want to have in this area. You can pick any function
except kmain and memcpy. What remains to be done is to select a set
of functions that is present under every configuration and optimally
uses the 3 KB of high memory.
Regards,
Jochen
