That shouldn't be the case IMHO, and most of the time it isn't at least not when building Qt.

In this case it's mostly to obtain the most compact build possible, esp. since I'm using a static build of libQtHelp . On Linux the size difference is considerable for the assistant executable (a factor 2-3 IIRC). It's not a great deal otherwise, just something I like to understand.
