[Scons-users] Fwd: Re: has overriding C++ compiler paths and names changed with Python 3.x?

[Eric Fahlgren]

I just upgraded from 3.0.1 and don't see this problem.  Using VS 2017, Win
10, Py 3.7, finds the compiler just fine, although my Visual Studio hasn't
been updated for 5-6 months...

(I did hit a catch on the renaming of Scripts/scons.py to just
Scripts/scons, though.)
