I put that code into hello.c and compiled. Yes, there are some warning:
$ dmd hello.c
In file included from <command-line>:
/usr/include/dlang/dmd/importc.h:101:8: warning: undefining "__has_feature"
101 | #undef __has_feature
| ^~~~~~~~~~~~~
/usr/include/dlang/dmd/importc.h:104:8: warning: undefining
"__has_extension"
104 | #undef __has_extension
| ^~~~~~~~~~~~~~~
I don't know what they mean. My compiler is this:
$ dmd --version
DMD64 D Compiler v2.109.1
But at least the linked program works:
$ ./hello
Hello World!

Which compiler? Were there any error messages?

Possibly. As a reminder, here is the download page.
