Again, cygwin-patches is for patches to the cygwin DLL, not for GCC
patches.  I'm politely telling you that you're sending your report to
the wrong address so please send you request where it belongs.

Even then, this doesnt make it an issue for the cygwin-patches ML.

You seem to misunderstand how this works.  The package maintainers of
the various Cygwin packages are not subscribed to cygwin-patches.  This
mailing list servers only the purpose to send patches for the Cygwin DLL
and accompanying tools, as outlined on https://cygwin.com/lists.html.
So, if you want to reach out to the Cygwin GCC maintainer, please send
your request to the cygwin AT cygwin DOT com mailing list, as outlined
on https://cygwin.com/lists.html.  Insisting on using the wrong mailing
list will not really help to move your complaint forward in the long
run.

So, please don't follow up on cygwin-patches, it's the wrong addressee.
