Discussion:
  Fred: Have we resolved how we are working as a subgroup of WG14? Two 
wikis for example.
  Jim: Not going very well since he is still doing double posting. Awkward 
situation.
  Rajan: Is Secure C doing this? They seem to be doing their own on the 
side without too much WG14 impact.
  Fred: Prefer keeping this separate

Part 2 review:
  Jim: I want to make this follow Part 1 by one WG14 meeting. This means 
we can have a WG14 review in May or June for this.
  Example 3 on page 29: Output is in "e" format now.
  Jim: A number of other editorial changes made.
 
Part 3:
  This Spring 2013 meeting will be the first time the full WG14 will see 
Part 3.
  This means we need Part 4 draft for early September to get into the 
October mailing.
  The changes to the type system is risky so needs to be looked at 
closely.
  Issue: quantexpd* functions may have the exponent > INT_MAX so the 
return type would not work (overflow)
  *I can send a note suggesting _DecimalN as the return type
  Type generic should be looked at still.
