gedit syntax highlighting for assembler files (*.asm)

Apparently the language definition provided on the extra language definitions page is not working with gtksourceview-4.0
I changed the file a bit and it works for me. The updated version can be found here.
Also here is a version for the 8086 (I have limited knowledge when it comes to XML and gtksourceview, feedback is welcomed)

The following steps should be enough.

wget http://www.carminebenedetto.net/_downloads/asm-intel.lang
sudo cp asm-intel.lang /usr/share/gtksourceview-3.0/language-specs/

Note that the exact folder to copy the .lang file to depends upon your version. You may have gtksourceview-2.0 instead, or even something else. On my machine I had both 2.0 and 3.0, and copied the file into each one's language-specs subfolder.

I tried the suggested links but to no avail. However the package found in link below worked for me.
