15.8 finally fixed the compiler bug and starting with preview 4 I also got a
good executable out. Had problems here with preview 3.
15.8 needs a configure fix for _RAISE.
Only compiled the comm-esr52 tree with backports to support VS2017 and
comm-esr60 right now. Only x64 too.

FWIW, I found that building with clang-cl works fine out-of-the-box
with 15.7.x, and the Installer tells me that I don't have the 15.6
toolset installed. YMMV, but I've found that clang-cl builds Just Work
with 15.7.

Hello all,
being among those unfortunate enough to have updated Visual Studio
before realizing that the most recent version cannot be used to build
Firefox, I was faced with the prospect of reinstalling the whole
monstrosity - which takes forever - or finding a workaround. As it turns
out I found a clunky yet simple one:
- Launch the Visual Studio Installer, the click on the "modify" button
- Go into the "Individual components" and select the "VC++ 2017 version
15.6 v14.13 toolset" component
- Launch the installation
- Modify build/moz.configure/toolchain.configure by manually setting the
tools_version string in [1] to the value '14.13.26128'
- You're done! Both a clang-cl and a msvc should now pick up the old
tooling and work properly (provided you have the right Windows SDK).
I couldn't find a way to override this via mozconfig options or
environment variables but if there is a way to do this without modifying
the sources I'd like to hear it.
