dynamic built fun and records

[Ulf Wiger]

I can see two options:

- Use epp for pre-processing. This will be a bit
   more complex, but then you can pass record definitions
   as well.
- The OTP R10 shell is supposed to understand records.
   Perhaps you could check the code and see if you
   can steal something? I haven't looked at it much,
   but it seems to involve some use of the undocumented
   module sys_pre_expand (in the compiler application.)
