This list could be this short:

-Zc:forScope -Zc:wchar_t  -wd4675 -EHs -TP -c

And sometimes it could be just -TP -c. The question is: should we
specify -W3 explicitly if -W3 is by default?

Without -W3 user would be able to specify cflags=-W4 without getting a
warning. And one more question: should we specify -W3 if a user
requests <msvc_warning_level>3 explicitly?

Should the toolsets know about default values for all supported
options? Should they display [Implicit options: -W3 -EHc] in a debug
log?
