Thanks.  Today I have to modify those files as well.

If I insert an include statement at the top of lex.cc, the
compile continues.  However, lex.cc is not part of the developer
sources:

        $ rm src/lex.cc && make -C src lex.cc
        /bin/sh ../build-aux/ylwrap lex.ll lex.octave_.c lex.cc -- flex -I -I

The generated lex.cc includes <config.h> about twelve hundred lines
in, where the contents of lex.ll appear.  But <string.h> is included
in the generated output up near the top of the file.  Is there a
"right" way to include <config.h> near the top of lex.cc, since that's
apparently a gnulib requirement?

Thanks.  In my original message I described a second failure in
builtins.cc.  My build now stops there.  Should I re-post details to
this list?

Thanks,
Rob
