`AM_PROG_LEX` calls `AC_PROG_LEX` with no arguments, but this usage is deprecated. The only difference between `AM_PROG_LEX` and `AC_PROG_LEX` is that the former defines `$LEX` as "./build-aux/missing lex" if no lex is found to ensure a useful error is reported when make is run. How- ever, the configure script checks that we have a working lex and exits with an error if none is available, so `$LEX` will never be called and we can replace `AM_PROG_LEX` with `AC_PROG_LEX`.
