Thank you, that seems to have been the source of the error.

This is equivalent to `WNDCLASSEXA WindowClass =
WNDCLASSEXA.init;`
If the struct's fields all initialize to 0, the compiler would
simply set the variable's bytes
I have included the source to a simple 64-bit Windows program.
It compiles and runs fine with ```dmd -m64
-L="/Subsystem:Windows" -L="/Entry:Main" Main.d```. But compiling
with ```-betterC``` using the following throws up a linker error,
```dmd -m64 -betterC -L="/Subsystem:Windows"
