This is failing on Windows:

17:28:56 c:\workspace\node-compile-windows\src\api\exceptions.cc(240): error C2440: 'reinterpret_cast': cannot convert from 'const char *' to 'HLOCAL' [c:\workspace\node-compile-windows\node_lib.vcxproj]
17:28:56   c:\workspace\node-compile-windows\src\api\exceptions.cc(240): note: Conversion loses qualifiers

I think we should leave this with

Suggested change
LocalFree(HLOCAL(msg));
LocalFree((HLOCAL)msg); // NOLINT(google-readability-casting)

because there is a bug in the API and what we really need here is:

    LocalFree(const_cast(char*>(msg));

but that's just as bad for tidy.

Windows fail is real:

 c:\workspace\node-compile-windows\src\api\exceptions.cc(240): error C2440: 'reinterpret_cast': cannot convert from 'const char *' to 'HLOCAL' [c:\workspace\node-compile-windows\node_lib.vcxproj]

Because what we really need is a const_cast.

FTR: This probably need using // NOLINT(google-readability-casting), but cpplint.py rejects NOLINT types it does not recognize. I'm planning on fixing that.

Revert to the original one and add // NOLINT(google-readability-casting) after we resolve cpplint issue ?

Thinking about this again, let's just use the const_cast and at some point in the future fix all const_casts
