    Hi Andy,

  Bash wasn't one of the packages updated - we've been on bash 4 since
February last year, and I already had it installed last september when I was
successfully using cygport to build the gcc-4.5.3-1 release.  So I figure that
the 4.x set -e behaviour might be part of this problem, but there must have
been a change in cygport that's exposing it when it was previously hidden.

    cheers,
      DaveK


PS. Hope everything's well with you and happy new year!  We should arrange a
pub meet sometime soon on the pig list.
