Definitely. Ideally that would be shipped with Emacs just like 3rd party
libraries are.

It does not. It was a question to Andrea because I do not understand why we
can't use the OS dynamic linker. It is not related to the MSYS issue.
The freloc table stores a bunch of function pointers to internal Emacs
functions.
I think it would be cleaner to just declare each of those functions as an
"IMPORTED" function, which is equivalent to adding a line like this to
the generated code:
extern T a_function(T1, T2, ... Tn);
Then the dynamic linker will wire things together when loading the eln file.
Maybe I am missing something about how dynamic linking works.
