No, Windows builds just are slower. For some time the buildfarm has been 
reporting run times for various members, so there's plenty of data on 
this. For example, nightjar and currawong are respectively FreeBSD/gcc 
and WindowsXP/VC2008 members running in VMs on the same host. currawong 
takes three times as long for a buildfarm run even though it's doing 
less work.

cheers
