*/
/* outfile is the filename to be used instead of lex.yy.c */
/*
* These are not supported in flex 2.5.4, but we need them
* at the moment:
* reentrant produces a thread-safe parser. Not 100% sure that
* we require it, though.
* bison-bridge passes an additional yylval argument to ael_yylex().
* bison-locations is probably not needed.
