Following the same structure from most of the multiline comments in the
file, they tend to be 

/*
 *
 */

I thought it was a typo, and maybe this makes the whole file have a
uniform multiline comment style.

Well, while reading the file on a 80 columns width terminal, it breaks
lines producing results like:

/* Maximum runtime for e
ach instance */

/* dl_runtime / dl_deadl
ine */

among others.

In fact, most of the comments in the file follow the structure:

/* comment about var */
type 			identifier

You can see this structure in lines:

631
689
740
781
820
among others.
