NO_RETURN is defined in config.h, like this:

474 #ifndef NO_RETURN
475 #if defined __GNUC__ && (__GNUC__ > 2 || (__GNUC__ == 2 &&  
__GNUC_MINOR >= 5))
476 #define NO_RETURN       __attribute__ ((__noreturn__))
477 #else
478 #define NO_RETURN       /* nothing */
479 #endif
480 #endif

maybe is skipped by line 475.

IMHO, config.h was included. But could you teld how to confirm it?

I havn't known how to resolve this problem.
