It is past time to change the default. I suspect a lot of the difficulties in porting are not just from pointer sizes but also integer sizes. Specifying "long" because the docs for an API say to use a longword is a 40-year-old habit that will be hard to break, and not all of the APIs have 64-bit equivalents. A lot of things probably assume "long" is the same size as "int" even though that is now no longer the case. As far as I know there is no compiler switch to say /DATA_MODEL=ILP32 to override the new default of LP64.
