You don't have access to druntime/Phobos stuff at runtime.
SimpleDllMain is for initializing and uninitializing druntime.

You want to only use ldc atm. The defaults right now should
most likely "just work" in dub for a single compile + link step
(i.e. only a single static library in dll).
If you do it manually, you'll want to add the flag
``--fvisibility=public`` to export everything.
I'm not sure I understand every bit of it yet, but this looks
helpful, thank you.
I was able to compile this (based on dllmain.d linked by you)
with both DMD and LDC:
```D
module WindowsApp1;
version (Windows)
{
version (D_BetterC)
{
import core.sys.windows.windef : HINSTANCE, BOOL, DWORD,
LPVOID;
extern (Windows) BOOL DllMain(HINSTANCE hInstance, DWORD
ulReason, LPVOID reserved)
{
return true;
}
}
else
{
import core.sys.windows.dll;
mixin SimpleDllMain;
}
}
export extern (C) void foo()
{
import core.stdc.stdio : printf;
printf("Hello betterC\n");
}
```
What's the reason to prefer LDC over DMD?
