A better way is to dynamically fix header files. This was suggested
in the discussion regarding the change to the header search implementation.
One way might be similar to that used for web pages in browsers. If
a header "changes", a cache of fixes could be updated. As a result,
gcc wouldn't get out of date. The private include directory of gcc
would disappear.

I didn't follow that discussion, but it's a pretty slick idea. It would
solve the problem of how to deal with installing vendor patches which tweak
header files after GCC was installed.
Do you know if anyone is working on this?

It wouldn't totally disappear as GCC still has its own varargs, stddef
and a few other header files. But what would disappear would be the
slightly modified copies of the vendor's include files.

Not that I am aware of. It was Paul Eggert's suggestion:
