Thanks.  I think we should do this on master, but on the release
branch compile gv.el AOT, as that will be safer.  WDYT?

Dependency in what way?  maybe if one installs from a Linux distro,
Binutils will be installed as a dependency.  But if someone downloads
a precompiled libgccjit DLL on Windows, for example, they will not
have Binutils unless they also install it.  Because libgccjit is part
of GCC, and one can AFAIK install MinGW GCC without installing
Binutils.

So I think my question still stands.
