How to compile EEL source for x64 ?

[FelixMagi]

How to compile EEL source for x64 if I changed a function? I see asm-nseel-x64.obj object which works but need to change it.

How to make this object from scratch? I tried php a2x64.php file, but ml64.exe give me this errors:

I build asm-nseel-x64.asm from asm-nseel-x86-msvc.c
