error in line
```typedef float _Float32;```
clang can compile that line,
but dmd or ldc can not!
This is definatly compiler error!
It is not an error..
This is just lack in the implementation.

Somehow it is working on macOS - aarch64, and not working on
Linux 864
I found possible solution
This error occure with inclusion of
"/usr/include/bits/floatn-common.h" system lib
to prevent error you can define __GNUC__ to be greater than 7
(for example - comment definition)
//lib.c
#define __GNUC__ 8
#include \<bits/floatn-common.h>
//
clang -c lib.c # compile OK
dmd -c lib.c # compile OK with WARNING
lib.c:1:9: warning: '__GNUC__' macro redefined [-Wmacro-redefined]
1 | #define __GNUC__ 8
| ^
\<built-in>:7:9: note: previous definition is here
7 | #define __GNUC__ 4
|
