This is due to the newlib library detection kludgery further up the file. Rather than using autoconf to probe the interface, we detect newlib, bypass the AC_CHECK_FUNC_ONCE() macro and hardwire the interface. This has the effect of leaving various ac_cv_func_* variables undefined.... Cheers /Marcus
