  tests: explicitly state that our lexers do not require unistd.h
  
  By default, GNU flex generates code that is dependent on unistd.h,
  which is not portable to non-ANSI systems causing spurious test
  failures.
  
  * tests/cond35.test (tscan.l): Define YY_NO_UNISTD_H.
  * tests/lex-clean.test (lexer.l): Likewise.
  * tests/lex-depend.test (joe.l): Likewise.

  the never-interactive option to prevent usage of the non-ANSI
  function isatty(3) (from unistd.h).
