          Issue ID: 23729
           Summary: ignore custom object.d for CTFE needs
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: ryuukk.dev gmail.com

Hello,

I use a custom runtime because i need that for WASM and other reasons

My runtime is minimal, it doesn't include bunch of stuff on purpose

I encountered an issue on Linux only (on windows it compiles and runs fine)

```
// dmd -betterC

import core.atomic;

int count;
extern(C) void main()
{
  atomicStore(count, 0);
  count = (atomicFetchAdd(count, 1) + 1);
  count = (atomicFetchSub(count, 1) - 1);
}
```

My custom object.d:

Windows: all good

Linux: 

```
dmd -betterC app.d
