Thanks for the tip. I found it - it is directly in the compiler.

In comprsrc.pas TWinLikeResourceFile.IsCompiled there is a logic that 
defines what the compiler does with the included resource file based on 
the extension or file header.

I don't like the fact that there are hard-coded constants for what seems 
to be (for a stranger) arbitrary file extensions and that it is not 
documented anywhere.

I will raise the question in the FPC mailing list.
