Microsoft's C++ standard library recently merged microsoft/STL#4405 to remove the internal `_STRINGIZE` macro. `chakracore` was using this MSVC internal macro, so `avoid_msvc_internal_STRINGIZE.patch` was added to adapt it to the microsoft/STL changes. Reference: chakra-core/ChakraCore#6970. - [x] Changes comply with the [maintainer guide](https://github.com/microsoft/vcpkg-docs/blob/main/vcpkg/contributing/maintainer-guide.md). - [ ] ~SHA512s are updated for each updated download.~ - [ ] ~The "supports" clause reflects platforms that may be fixed by this new version.~ - [ ] ~Any fixed [CI baseline](https://github.com/microsoft/vcpkg/blob/master/scripts/ci.baseline.txt) entries are removed from that file.~ - [ ] ~Any patches that are no longer applied are deleted from the port's directory.~ - [x] The version database is fixed by rerunning `./vcpkg x-add-version --all` and committing the result. - [x] Only one version is added to each modified port's versions file. --------- Co-authored-by: Monica <[email protected]>

Avoid using MSVC-internal _STRINGIZE chakra-core#6970 Below is the comment from Stephan T. Lavavej in the above mentioned pull request: "I work on Microsoft's C++ Standard Library implementation, where we recently merged microsoft/STL#4405 to remove our internal _STRINGIZE macro. Our "Real World Code" test suite, which builds popular open-source projects like yours, found that you were using this MSVC-internal macro and therefore our change broke your code. The C++ Standard's rule is that _Leading_underscore_capital identifiers (including _LEADING_UNDERSCORE_ALL_CAPS) are reserved for the compiler and Standard Library, so other libraries and applications should avoid using such reserved identifiers. This is N4971 5.10 [lex.name]/3: In addition, some identifiers appearing as a token or preprocessing-token are reserved for use by C++ implementations and shall not be used otherwise; no diagnostic is required. — Each identifier that contains a double underscore __ or begins with an underscore followed by an uppercase letter is reserved to the implementation for any use. This PR introduces non-reserved names that will work on all platforms."
