#include "np_regex.h"

(in np_regex.h, do this)
#ifndef HAVE_REGEX
#define regex_t char
#define regmatch_t char

static void no_regex_support(void)
	die("Sorry. regex support not available on this platform\n");

int regcomp(regex_t *a, const char *b, int flags)
	return 0; /* musn't upset the compiler */

With similar replacements for regfree(), regexec() and regerror().
No #ifdef's, no hassle and no bloat.
