Move the %options to the beginning if they weren't already there, and put them in the same order in all files. Add "prefix=" options to .l files that don't already have them, so we don't have to pass a "-P" option. Add "never-interactive" and "noyywrap" options to our lexical analyzers, to remove extra isatty() checks and to eliminate the need for yywrap() from the Flex library. Get rid of %option nostdinit - that's the default. Add .l.c: rules to Makefile.am files, replacing the rules for specific .l files. Have those rules all check that $(LEX) is set. Update the address for the FSF. svn path=/trunk/; revision=22424
