I think you should address the following regression caused by
v1.11-284-g34ca92b before merging.

If you configure on a system w/o any lex and/or yacc, you will suffer
from spurious failures as the lex/yacc required= in the testsuite no
longer works in that case.  defs relies on being fed LEX=false and
YACC=false from the Makefile when there is no lex/yacc, but that is
no longer true after the above commit.  Dozens of tests then FAIL
since they assume think lax/yacc is present.  Below is the log from
lex-depend.test, but that is just an example. Note that the lex
configure think it has found is just the default if no lex is
located.

Cheers,
Peter
