• AIX: display OS version better (tested on 5.3 by cnuke@)

• IBM XL C: display version better (tested on V7.0 by cnuke@)
• do not 'IFS=: read nr name', Cygwin 1.7 dash fails it
• disable cd-pe, glob-range-3 on Cygwin (the former cannot
  succeed because the mv fails, the latter fails from 1.7 on)
• mark heredoc-tmpfile-8 as need-pass: no
• apply __attribute__ only to a function prototype, not to
  the body (even if static), since xlC fails that
• bump version to R40 (beta)
