I don't really care which separator is used. You can remove the `` character. We don't need to spend too much time on this.

I don't know what the error message you get, but `^` definitely works for me as continuation line marker in `cmd.exe`.


C:\dev\jdk-dev>cl -I %OPENJDK%\src\java.security.jgss\share\native\libj2gss\ sspi.cpp ^
More?    -link -dll -out:sspi_bridge.dll
'cl' is not recognized as an internal or external command,
operable program or batch file.


This `More?` prompt identifies the continuation line.

Anyway, we decided to leave it as is but convert to multi-line comment, which is fine with me.
