llvm compilation error from non-standard use of std::basic_string / std::char_traits #342
Description
On OSX, I've started encountering llvm compilation errors after updating to 15.4. I believe these are fixed in upstream SFML by:
Newer versions of llvm have started erroring out over usage of std::basic_string with non-char types, which apparently is non-standard but supported until now.
Example error (many are emitted):
