configure uses AC_CHECK_DECLS to check for _NL_TIME_WEEK_1STDAY
which means we will get HAVE_DECL__NL_TIME_WEEK_1STDAY
defined to 1 if symbol is declared, otherwise to 0 in config.h

Therefore we cannot rely on conditionals which check for it
being defined or not since it always will be defined so correct
thing is to use #if instead of #ifdef
