`QVFuncList` and `QStartUpFuncList` are identical typdefs
(`QtCleanUpFunction` and `QtStartUpFunction` are identical typedefs):
typedef QList<QtCleanUpFunction> QVFuncList;
typedef QList<QtStartUpFunction> QStartUpFuncList;
So from the compiler's POV QVFuncList and QStartUpFuncList can be used
interchangeably, but from a code reader's POV, this is confusing.
Use IILE to make the local variable const.
