The extern statement seems to have worked;

/** \file xatof.c
 * Implements xatof, an easy to use strtod() wrapper.
 *
 * \author Matthias Andree
 * \date 2003
 */

#include "xatox.h"

#include <string.h>
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>

extern double strtod (char *, char **);

...

[cahewson] ./Bogofilter-new/bin/bogofilter -C -D -v -M -o0.45,0.4 -Q
sc 0.0000, hc 0.0000
val 0.4500
val 0.4000
sc 0.4500, hc 0.4000
# bogofilter version 0.92.6

Grep doesn't like -r on SunOS;

[cahewson] grep -r -w strtod /usr/include/
grep: illegal option -- r
usage: grep [-[[AB] ]<num>] [-[CEFGVchilnqsvwx]] [-[ef]] <expr>
[<files...>]
