pitrou opened a new issue, #46272: URL: https://github.com/apache/arrow/issues/46272
### Describe the enhancement requested gcc has a warning option [`-Wmissing-declarations`](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wmissing-declarations) that should allow us to find private functions that erroneously have global linkage (because they are neither `static` nor in the anonymous namespace). Enabling this option will probably produce many false positives, though, and they will have to be worked around. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
