Being a paranoid programmer myself, I always use:
  sub remove_trailing_newline {
    $_[0] =~ s/[\r\n]+\Z//;
  }

[download]
no matter which platform I am on. A real trick is trying to find blank lines in a slab of (multiline) text:
  if ( m/(\r\n|\n\r|\r|\n)$1/ ) {
    # two newlines in a row!
  }

Update: Thanks to rev_1318 for pointing out that the $1 need be replaced with \1 in the regexp.
