Re: Warning when compiling with -pedantic, and fix

As Splint isn't able to parse macros with (...) parameters, it's even 
better to add defined (S_SPLINT_S) like this:

#if defined (__STDC_VERSION__) && __STDC_VERSION__ >= 199901L
#define nerr_raise(e,f,...) \
    nerr_raisef(__PRETTY_FUNCTION__,__FILE__,__LINE__,e,f,__VA_ARGS__)
#elif __GNUC__ > 2 || (__GNUC__ == 2 && __GNUC_MINOR__ >= 4) || defined 
(S_SPLINT_S)
#define nerr_raise(e,f,a...) \
    nerr_raisef(__PRETTY_FUNCTION__,__FILE__,__LINE__,e,f,##a)
#else
#error The compiler is missing support for variable-argument macros.
#endif
