Issue with AM_PROG_LEX

Hello,

I have a configure.ac file that calls AM_PROG_LEX. This now generates warnings:

> configure.ac:4045: warning: AC_PROG_LEX without either yywrap or noyywrap is obsolete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...
> aclocal.m4:9472: AM_PROG_LEX is expanded from...
> configure.ac:4045: the top level

I am not sure I can actually fix those: AM_PROG_LEX does not seem to accept an argument. Probably it should, and pass it down to AC_PROG_LEX if provided? So this seems to be a bug in automake, or am I missing something?

Thanks,
FX
