            Bug ID: 42826
           Summary: Error reporting of clang-cl changed in 9.0.0-RC1
           Product: clang
           Version: 9.0
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P

When compiling a file that contains an error,
clang 5.0.0-8.0.0 report this as:
filename(linenr,columnnr):<space><space>error: message

>From clang 9.0.0 on, this was changed to:
filename(linenr,columnnr):<space>error: message

Our internal build tool and reporting in CIs parses this output based on this
error-tag. This is now broken.

I'm not really attached to the way this format looks like, as we can update it.
However, if it ain't an intentional change, it would be nice that we can use
the same scripts for all versions of clang.
