I'm not following you. If I type C-u M-x occur RET gcd_hook RET, I get
an *Occur* buffer looking like this:
3 matches for "gcd_hook" in buffer: gcd.c
: mp_size_t gn;
:};
:
:static void
61:gcd_hook (void *p, mp_srcptr gp, mp_size_t gn,
: mp_srcptr qp, mp_size_t qn, int d)
:{
: struct gcd_ctx *ctx = (struct gcd_ctx *) p;
: MPN_COPY (ctx->gp, gp, gn);
-------
: }
: else
: {
: /* Temporary storage n */
209: n = mpn_gcd_subdiv_step (up, vp, n, gcd_hook, &ctx, tp);
: if (n == 0)
: goto done;
: }
: }

This is with emacs-23.2, but I think it's the same in other emacs
versions I have used. The documentation string for occur says
Each line is displayed with NLINES lines before and after, or -NLINES
before if NLINES is negative.
NLINES defaults to `list-matching-lines-default-context-lines'.
Interactively it is the prefix arg.
> Have you tried `M-x occur M-n RET'?
Now I have. Seems to give the symbol at point in recent emacs versions.
Slightly less convenient than a prefix argument, but I think that does
what I want.
