It comes because AM_PROG_LEX calls AC_DECL_YYTEXT, and in the new
version of autoconf these macros is the same. It does the right thing,
the resulting configure script is correct. I have sent an error-report
to the automake developers, but i don't think they will do any thing
about it. The call to AC_DECL_YYTEXT is needed for older versions of
autoconf, so they can't just leave it out. But i think it should be
possible to decide if AC_DECL_YYTEXT needed to be called based on the
version of autoconf. I think it is very annoying to get a warning even
if the configure.in is correct - not to mention the time wasted on
investigate the warning.
