--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
It has been the same as -isystem since at least r0-21114-g0b22d65c9a10ce (March
1999).
The documentation was changed (added to) at r0-35796-gf3c9b8530c78ce (June
2001) to specify the same as -idirafter even though the implementation was
something different ....

I don't know what the correct thing to do really since it has been almost 22
years of having the documentation not match the implementation ...
Maybe just update the documentation ....

Confirmed either way.
