  fix memory leak on error (from Coverity scan)
  Fix coverity issue with -1 returned by findOffset not being handled by getPreferredTag
  5.4.21 release date
  fix argument type & remove warning
  fix const warnings in intl methods
  When src->src is null this doesn't get initialized but it is still used, so the passed in *ze will point to unitialized memory. Hopefully src->src is never null, but just in case this initialization doesn't hurt.
  Fix coverity issue with -1 returned by findOffset not being handled by getPreferredTag
  fix possibility of access to *storedType without initialization
  5.4.21 release date
  Fix typo
  These getpwnam('') tests are silly and not portable
