The text_64k linker script only allows coderes to grow beyond 32K. When you look at how your program is linked, you'll see the first file is crt0.o. The start routine (which also calls your PilotMain) is also calling the bhook, ehook and constructor/destructor functions. These get linked in from the C-library (libcrt.a) and placed after all your routines. Since the calls in start.o use signed 16-bit relative addressing (DISP16) you still have the 32K limit. In your case the routines cannot be reached from start.o. Ome way out is to manually arrange your object files in such a way that no routine called is more than 32k away from the callee. In your case you will have to force hooks.o and multi_dreloc.o from the library within 32K of the start of the .text segment.
