// WORKAROUND: The old prototype for this function was:
// template<class T> T *load(Common::File *fd, uint32 ofs);
// that caused a parser error in g++ 3.3.6 used by our
// "motoezx" target of our buildbot. The actual parser

// "T *result = _dataCache->load<T>(_scriptFile, _data[value.value]->offset);"
// in ScriptInterpreter::toData. To work around this
// we moved the return value as parameter instead.
