:P

I have posted here sources and binaries of the stable JWasm13 version
There is no AVX512 in this version
I had to post it separated because of the forum limit
All you need to do is to decompress both folders and than drop the H folder in JWasm13 folder.
It is important to use these headers otherwise you will not have the latest important fixes To build it with Visual Studio 2013 Community you have to change only the location of the H folder
Chhange:Project->
JWasm Property Pages->C/C++->Adittional Include Directories:
C:\Users\Brane\Documents\Visual Studio 2013\Projects\JWasm\H
to your path or you can replace it with
..\\H
