So if I wanted to write a user-config.jam, will just simply placing it in
the same place as where the project-config.jam cause boost to detect the
user-config.jam? Basically, the property that my platform is missing is the
<addressing model>. In other platforms I have seen this property as
<address model>32 and <address model>64, but on aix the tag doesn't even
show up. It just doesn't exist for whatever reason. Do you think writing a
user-config file where I add it manually is worthwhile? Because with the
user-config file I could also just simply write the flags I'm passing in as
part of my build right? That in my opinion would make the most sense.

Sincerely,
-Axel

A feature can have a default value which is determined
when the property is defined (see builtin.jam).  If a
feature has no value when building a target, then it must
have been declared as optional.  Properties can be specified
on a target, for a project (including user-config.jam),
or on the command line.

It depends on what you're trying to achieve.
