I create a DLL project: Properties -> General -> Output Type = DLL, Subsystem = Windows
I get the error when linking:
error LNK2019: unresolved external symbol WinMain referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ)
Seems to want WinMain, even though it's a DLL.
If I change 'Subsystem' to 'Not Set', it complains that main() is missing instead.

Seems that it expects '/DLL' given to the linker, but it's not.
I added -L/DLL to additional options and it links.
This should probably be there automatically.

I noticed this too recently. This only happens when using the MS linker (also for 32-bit DLLs), not with optlink.

Ah, I don't think I've ever used optlink since your 32bit COFF work was merged ;)
