PPC G4 "Velocity Engine" supported

Hi,
this might be a stupid question, so please excuse in advance...
On Apple's website there is a description of the G4 PPC CPU:
http://www.apple.com/powermac/processor.html
...basically, this CPU seems to support some special floating-point
vector extensions. Are these extensions supported by g++ in some way?
Means, when I compile a program, how can I make sure that the G4's
vector extensions are used to speed up my code? Is it necessary to
address these extensions by direct assembler coding?
Thanks for your help!
Rolf
