After this patch it is very hard to build lldb on Windows. We got the errors like the following
```
D:\llvm-project\lldb\source\Plugins\ScriptInterpreter\Python\Interfaces\ScriptedThreadPlanPythonInterface\ScriptedThreadPlanPythonInterface.cpp: 
fatal error C1041: cannot open program database 'D:\build-lldb\tools\lldb\source\Plugins\ScriptInterpreter\Python\Interfaces\ScriptedThreadPlanPythonInterface\CMakeFiles\lldbPluginScriptInterpreterPythonScriptedThreadPlanPythonInterface.dir\lldbPluginScriptInterpreterPythonScriptedThreadPlanPythonInterface.pdb'; 
if multiple CL.EXE write to the same .PDB file, please use /FS
```
Note MAX_PATH is 260 on Windows. But the length of the path to .pdb is 262.
It is necessary to use 7 chars or less folder in the root of a disk to build lldb on Windows using Microsoft VC++. 
You must reduce the length of the paths.
