With autoconf 2.70, the following warnings are emitted: configure.ac:56: warning: AC_PROG_LEX without either yywrap or noyywrap is obsolete ./lib/autoconf/programs.m4:716: _AC_PROG_LEX is expanded from... ./lib/autoconf/programs.m4:709: AC_PROG_LEX is expanded from... configure.ac:56: the top level The documentation[1] of autoconf now states: > Prior to Autoconf 2.70, AC_PROG_LEX did not take any arguments, and > its behavior was different from either of the above possibilities: it > would search for a library that defines yywrap, and would set LEXLIB > to that library if it finds one. However, if a library that defines > this function could not be found, LEXLIB would be left empty and LEX > would not be reset. This behavior was due to a bug, but several > packages came to depend on it, so AC_PROG_LEX still does this if > neither the yywrap nor the noyywrap option is given. > > Usage of AC_PROG_LEX without choosing one of the yywrap or noyywrap > options is deprecated. It is usually better to use noyywrap and define > the yywrap function yourself, as this almost always renders the LEXLIB > unnecessary. The behaviour of the argument on autoconf < 2.70 is to ignore the argument, so there are no issues with adding the option.
