It is for what users perceive. A user upgrades from GCCn to GCCn+1 on their existing hardware. If n+1 is slower, they get annoyed. When that user upgrades their hardware, they say 'hey my *computer* is faster', not 'hey gcc is faster'. Their expenditure on new faster hardware does not get them faster development cycles, if gcc eats it all up. nathan -- Nathan Sidwell :: http://www.codesourcery.com :: CodeSourcery LLC nathan@codesourcery.com :: http://www.planetfall.pwp.blueyonder.co.uk
