"overriding" can be done pretty simple, like i mentioned above already....
just put the additional (or replaced) functions into a seperate library and
put this last on the linker commandline..... this however is somewhat tricky
for functions that are simply defined as kernal-calls inside the conio lib
(eg the "kplot" call which you have to patch for a new conio driver)... this
may be actually a flaw in the linker, it didnt always do what i expected
atleast :o)
