Ah, OK. I thought my test case had _GNU_SOURCE defined already,
but it didn't. You might want to do something like what I stuck
in for strchrnul, though:
/*
* glibc's <string.h> declares strchrnul only if _GNU_SOURCE is defined.
* While we typically use that on glibc platforms, configure will set
* HAVE_STRCHRNUL whether it's used or not. Fill in the missing declaration
* so that this file will compile cleanly with or without _GNU_SOURCE.
*/
#ifndef _GNU_SOURCE
extern char *strchrnul(const char *s, int c);
#endif
