I don't get that from the docs:
http://www.freepascal.org/docs-html/prog/progsu102.html#x110-1100001.2.26

first line:

"A unit that is compiled in the {$SMARTLINK ON} state will be compiled in such a way that it can be used for smartlinking."

As far as I can see when linking wiht -s, and objdumping the .o of the mainprogram, I'd say FPC has nothing to do with it.

That routine looks like the coff assembler. IOW, it could be that the header is the header for each .o ?

Depends. For such a change, some testing needs to be done by people that actually understand dos/dpmi issues. I don't. Filing a bug about it can help avoid it being forgotten, and act as a kind of forum to discuss it and exchange epxeriences
