I think it's not a syntax class, but a flag as described here :
(info "(elisp) Syntax Flags")
--8<---------------cut here---------------start------------->8---
* `p' identifies an additional "prefix character" for Lisp syntax.
These characters are treated as whitespace when they appear between
expressions. When they appear within an expression, they are
handled according to their usual syntax classes.
The function `backward-prefix-chars' moves back over these
characters, as well as over characters whose primary syntax class
is prefix (`''). *Note Motion and Syntax::.
--8<---------------cut here---------------end--------------->8---
I could suggest :
--8<---------------cut here---------------start------------->8---
--- a/src/syntax.c
+++ b/src/syntax.c

Is it any better ?
