Sounds like a question for the gnu-m68hc11 group
http://tech.groups.yahoo.com/group/gnu-m68hc11/
Since what you need is apparently syntaxt help for the gcc compiler.

Are you willing to overwrite d-bug12? You can't store a program in
flash on the DP256 unless you overwrite d-bug12. You can replace it
with the serial monitor, or just use a BDM device to put your program
in flash. But this may not be a good idea unless you understand this
issue pretty well.
