Yes, this does ultimately need to be fixed in automake, but in the meantime you *may* be able to work around it by writing

AC_PROG_LEX([noyywrap])
AM_PROG_LEX

(Change "noyywrap" to "yywrap" if you actually need yywrap from libl.a.)

This will work iff AM_PROG_LEX uses AC_REQUIRE to invoke AC_PROG_LEX. I'm writing this on my phone so I can't easily check.
