Yes, but there's a subtle difference:

^^^^^^^^^^^
IOW, the Emacs 27 build uses -static (thus linking against libgmp
statically), whereas the Emacs 28 does not. Which is why
libgmp-10.dll ends up being a runtime dependency of the latter, but
not the former.
I don't know how this happened, but hopefully this is a string you
could pull to find the reason(s). First question I'd ask is "how do
you arrange for -static to be injected into the link command line?"
Maybe whatever you do no longer works with the master branch?
