When the user installs an updated version of Visual Studio, the

Alternatively the whole vcpkg download may be cleaned allowing it to be
reloaded, though this may take much longer on slower connections.

Did you mean to send this upstream or to Git for Windows?
I didn't think that the VS2015/VS2017 vcpkg-aware version of
compat/vcbuild/* had made it upstream yet, so this patch might not
apply upstream.
Ah, that would be my mistake.
BTW, the Makefile (when MSVC=1 is defined) will take care of deleting
the MSVC-DEFS-GEN, so all we really need to say here is to do:
$ make MSVC=1 clean
or $ make MSVC=1 DEBUG=1 clean
after upgrading to a new version of VS.
It (my suggestion) was the difference between a deep clean of all the
1.05GB of vcpkg files, vs the 847 bytes of just the MSVC-DEFS-GEN file
that was a concern.
The need to repeat the download of 1GB just because of a VS version
change felt a bit excessive, hence the initial suggestion.

PS. I have a TODO item to fix the Makefile to automatically detect
and take care of this.
Thanks.
IIUC download of the vcpkg files are separate from the generation of the
MSVC-DEFS-GEN file - or are their inter-linkages?
