Another option for gcc is to apply __attribute__((noreturn)) to the Exit function definition in src/funcs.h, so the compiler knows the function never returns. void Exit(int status) __attribute__((noreturn)); ./WINGs/WINGs/WUtil.h (lines 31-33) already has the magic to make __attribute__ not break non-GCC compilers, BTW, although I don't know whether that is included whenever src/funcs.h is. -- To unsubscribe, send mail to wmaker-dev-unsubscr...@lists.windowmaker.org.
