I did. I followed his procedures. I will write a document specifying what I had
to do in English.

They link against the crt (C runtime) and some core Windows libraries. As I
replied to Eli, the main issue is that the assembler and linker expect to find
some support files from the MSYS installation. The easiest way is to just run
Emacs from a MSYS shell. Another way would be to create a "stub installation" of
MSYS inside the emacs installation dir copying only the files that are

The second way seems to be best, especially when you consider that shipping a
full MSYS installation alongside emacs is not a good idea.

PS: I don't understand why the freloc table is necessary. Is it impossible to
rely on the dynamic linker to solve that when calling dlopen()?
