clang-9 'no such file or directory' with Windows mapped drive and relative path

Hi all,

we noticed a problem with the upcoming clang-9 on windows.
When working on a mapped network drive, clang-9 does not seem to find files relative to the 'current directory'.
clang-8 does not show this problem.

Following steps (see below) can be used to reproduce this. We tested on a Windows Server 2016 machine.

Did anybody else see this behavior ?

Thanks,
