Crashing Cross-Development or... What is a Prefix File

<Obligatory Statement Of Defeat>
"I give up."
</OSOD>

My app compiled and ran on 10.3.
It compiles and runs on 10.4.
I'm trying to make compatibility build.
It runs on 10.4 but crashes instantly with EXC_BAD_ACCESS on 10.3.9
(trying to instantiate the application delegate from the main nib).

After a review of the docs and the archives...

I've got the Deployment Target set to 10.3.
I've got the SDK set to 10.3.9.

I read the docs again. Perhaps this is my problem:

For each target, supply a prefix file that takes into account the selected SDK. To use an umbrella framework header from an SDK as your prefix file, add the appropriate #include <Framework/Framework.h> directive to your target's prefix file, instead of setting a Prefix Header path to the umbrella framework header directly.

I seem not to have a prefix file (or it is very well hidden). I would dearly love to supply one and get on
with things but...


What is it ? What's in it and in what form ? Do I order one from the ACME company ?
The only mention of the phrase "prefix file" in the entire 452 page Xcode manual is in the above paragraph.


What do I have to do do learn the secret handshake ?
