src: disable unfixable MSVC warnings
Browse files Browse the repository at this point in the history
The following warnings are disabled:
- C4065 in node_revert.h: there are no security reversions on the master
  branch.
- C4003 in base64-inl.h: a macro is used four times, only once without
  parameters.

PR-URL: #37334
