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.
