That's not what needs to be done.=C2=A0 Emacs compiled for GnuTL= S versions
before 3.4.0 is incompatible with the GnuTLS DLL versions 3.4.0.=C2=A0 The<= br> new ABI introduces a binary incompatibility, so you need to recompile
Emacs with the newer GnuTLS headers to be able to load the 3.4.0 DLL.
And if you recompile Emacs like that, it will be incompatible with the
older DLLs.=C2=A0 Trying to load incompatible DLLs will likely cause a
crash.

So the change you need to do is more than just the one you show.

Once again, I don't recommend that, if you are building a binary for more than just your own consumption.=C2=A0 But that's up to you.
