Disabling RTTI on Clang on Windows prevents std::any from being defined. This does not happen when RTTI is left enabled, or with RTTI disabled on Clang on Linux.
**Repro**
main.cpp:
```
#include <any>
int main()
{
std::any a;
}
```
Errors generated with RTTI disabled (Windows only):
```
>clang++ -std=c++17 -fno-rtti main.cpp
main.cpp:5:5: error: use of undeclared identifier 'std'
std::any a;
^
1 error generated.
```
No errors generated with RTTI left enabled:
`>clang++ -std=c++17 main.cpp`
```
clang version 16.0.5
Target: i686-pc-windows-msvc
Thread model: posix
```
