libwinpthread-1.dll shouldn't be there. But maybe there's no way to
avoid that with MinGW64 ports of GCC. See below.

A more GNU-friendly way is
objdump -p emacs.exe | fgrep "DLL Name:"

Why are you asking us? The Emacs project doesn't build libgmp, it
only uses it. This question shouldf go to the GMP developers, IMO.

I guess this is some kind of regression. But I'm not sure we can
avoid this, when MinGW64 is used. (I use mingw.org's MinGW, and my
Emacs on Windows doesn't have the libwinpthread dependency.)
