  35     the struct inherits from a base struct and the first member is neither
  36     double nor sal_[u]Int64.  (The double/sal_[u]Int64 restriction is due to a
  37     bug in GCC prior to version 3.3, which would cause __alignof__ of such a
  38     struct to become 8 instead of 4 if CPPU_GCC3_ALIGN were added to its first
  39     member.)
