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.
