These errors indicate that the wrong assembler style is selected. Use Intel
mode: {$asmmode intel} 
This isn't going to solve your problem though. Variable parameters are 64
bit and passed in rax, rdx, not eax, edx. Pushing and popping registers
becomes push rsi instead of push esi. Register relative addressing is [rsi]
instead of [esi], etc. etc. etc.
