> The reason for this is src/Makefile uses ELN_DESTDIR and BIN_DESTDIR in
> rules, but does not contain definitions for them. In a toplevel make,
> both are defined on the command line when invoking "gmake -C src
> ELN_DESTDIR=...".
> 
> When making in src, ELN_DESTDIR is therefore empty, and temacs is called
> with with --eln-dest empty. Loadup.el then does its thing and calls
> load--fixup-all-elns before dumping. That function decides to not set
> native compilation units' file member to a cons, and "trying to dump non
> fixed-up eln file" is then issued when dumping such a CU.

> I don't know what the right fix for this is, maybe load--fixup-all-elns
