lld-link.exe: error: could not open msvcrt100.lib

[Andre Pany via Digitalmars-d-learn]

Hi,

lld-link was working fine on my windows pc. I set in global dub 
settings file
architecture to X86_64. DMD was installed by extracting the zip 
archive.

For python development ): I had to install "Build Tools for 
Visual Studio 2017".
Now dub (lld-link) fails always with error message:
lld-link.exe: error: could not open msvcrt100.lib: no such file 
or directory
lld-link.exe: error: could not open OLDNAMES.lib: no such file or 
directory
Error: linker exited with status 1

My assumption is, the Build Tools installation somehow confuses 
the link logic.
Is this a bug?

Kind regards
André
