Greetings!

From time to time I encountered issues on the subjected after I upgraded my dmd package.Given below code :

[...]

If it still doesn't work try adding this:

```d
pragma(lib, "user32");
pragma(lib, "comdlg32");
```

Another alternative if you're using dub is to add this in your dub.json instead:

```json
"libs": ["user32", "comdlg32"]
```

This seems be something related to DMD vs LDC. Because if I change the compiler to DMD I also get unresolved external symbols, but not with LDC.

It seems the forwarding of directives from submodules are different.
Thank you.

Below two pragma solved the isse but am confused as they are already in the system path.This is the first time I have to include lib files here.How come other gui programs don't have to do this.
pragma(lib,"user32");
pragma(lib,"comdlg32");

I'm not sure why, it works for me, but I think it could be something dmd does different. The pragma lib is inserted into the generated object file, or otherwise passed to the linker, so the linker automatically links in that library.

I'm guessing dmd for some reason does not see it in the submodule, but I have no proof that's the issue, I'm just guessing.

Really appreciated for the help.I am learning to understand.
Not using these two pragma in the source,other in the commandline:dmd -m64 user32.lib comdlg32.lib test.d compiled.But--- In an IDE say PoseidonD it still failed to compile even if I provided the library path to the compiler,I just can't understand how come my other small programs ( based on gui libslike DFL2,iup4D,dwt,NAppGui4D ) works fine without having to provide pragma in the source before compiling.

It's probably because these libraries already have the symbols
