[libc-commits] [PATCH] D154036: [libc] Add support for creating wrapper headers for offloading in clang

[Joseph Huber via Phabricator via libc-commits]

jhuber6 updated this revision to Diff 535835.
jhuber6 added a comment.

Semi-fix hack for `string.h` and fix `ctype.h`. `string.h` required undefining
C++ mode so we didn't use weird GNU C++ handling, which we then still need the
`extern "C"` for. The cytpe problems come from GNU defining everything as a
macro so it fails to redeclare.

The amount of hacks that just this has required so far is fairly convincing to
me that this is the more correct solution and should be separate from `libc`.
