Gentlemen, Thank you for your input but I found an option, -i, which turns off case sensitivity so I've made it past one problem but have a new one. Seems I'm getting a message "m68k-motorola-coff-ld: link errors found, deleting executable 'system.abs'." Anyway to turn on another option to detail the error causing this message? It is proceeded by another message, "fake: relocation truncated to fit: DISP16 maovfsub." Again, any thoughts as I can't seem to find any solutions for this problem. Yes, I'm compiling/linking for a 68k processor board.
