Re: tools-windows-msvc runtime error

I tried adding /INCREMENTAL:NO, but the issue persists.

Also the documentation says that incremental linking is disabled when =
the output file doesn=E2=80=99t exist, which is confirmed by this log =
after deleting the .exe:
> LINK : test.exe not found or not built by the last incremental link; =
performing full link
