But it is not the right long term solution.

  For C++, the default pointer size should have remained 32.
It was a mistake to change the default from what it was on Alpha and IA64.

 It was a mistake to use 32 and not 64 on Alpha and Itanium, but that pain will continue for the foreseeable future.

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.
