So far as I know this not a standard header - it is a GNU extension.

Flang supports other systems such as AIX, MacOS, Windows, and even other C libraries on gnu+linux systems (e.g. llvm-libc).

Please could you put this behind a preprocessor check so that compilation is not broken on those other systems.
