Darktable windows build help needed

Some issues to build dt on windows with last msys2 (msys2-x86_64-20180531, I’ve reinstalled it).
To reach the end of builds I had to downgrade lensfun (3.2.4) and graphicmagic (1.3.29).

Once launched dt crashes. I’ve attached the log.

Somewhere in the build I’ve seen something “32 bits detected” … while I’m running windows 10 64 bits. I don’t remember if I had this with the previous environment.
