In April 2020 I created a patch for the GNU C Preprocessor, with documentation, test cases and everything. I submitted it to the GCC Patches mailing list, exactly as comments in this ticket from 2015 advised me I should have done for this item back in 2008. I received absolutely no replies; not even to reject the submission. I "pinged" it a number of times, to no avail. The four year anniversary is coming up; I'm going to ping again. Then if I'm still ignored, one last time in April 2025.
