This reverts commit 68c04b0ae6.
This disables the IWYU mapping that caused the failure, since
the headers aren't reachable for now.
This is the first part of the "Freezing C++03 headers" proposal
explained in
https://discourse.llvm.org/t/rfc-freezing-c-03-headers-in-libc/77319/58.
This patch mechanically copies the headers as of the LLVM 19.1 release
into a subdirectory of libc++ so that we can start using these headers
when building in C++03 mode. We are going to be backporting important
changes to that copy of the headers until the LLVM 21 release. After the
LLVM 21 release, only critical bugfixes will be fixed in the C++03 copy
of the headers.
This patch only performs a copy of the headers -- these headers are
still unused by the rest of the codebase.

This usually means that your header search paths are not configured properly. \
|
|
The header search paths should contain the C++ Standard Library headers before \
|
|
any C Standard Library, and you are probably using compiler flags that make that \
|
|
not be the case.
