Subject: Visual Studio 2019 compiler errors not detected/recognized by compile.el

From: Bret Needle <[email-masked]>

Configuration:

 ?????? GNU Emacs 26.2 (build 1, x86_64-w64-mingw32) of 2019-04-13

 ?????? Microsoft Visual Studio 2019 (Community Edition)

Bug Behavior:

The default setting of the diagnostic mode option 
(/diagnostic:classic|column|caret) is now column when creating new C++ 
(VC) projects with VS 2019.?? This mode produces compiler error messages 
in the following format:

File name(line number, column number): error message ...

This new format is not recognized by the Microsoft (msft) regular 
expression check in compile.el.

Thanks,

Bret Needle ([email-masked])
