Bison 3.0 was released in 2013, and the current Debian stable (buster) has version 3.3.2. * m4/bison.m4: Remove -Wno-precedence and -Wno-empty-rule, keep -Wno-deprecated just to protect from future deprecation warnings that would be interpreted as errors. * spot/parseaut/parseaut.yy, spot/parsetl/parsetl.yy: Use %empty rules, prefer %precedence over %nonassoc, update %error-versbose and %name-prefix to their more modern equivalent. * spot/misc/trival.hh (maybe): Mark this function as noexcept to please the compiler while compiling the parsers.
