With the '$LEX --version' hang fixed, I get the attached log, with the
following failures:

You can ignore:
  - The failure of t/gettext-external-pr338 because I have an unreleased
    version of gettext on that machine, which has a dysfunctional 'autopoint'
    program.
  - The failures of *lex*, because that old version of 'lex' is not worth
    supporting.
  - The failures of subpkg*, because Solaris 'make' makes wrong variable
    substitutions in VPATH builds (well-known).
