Creating a DLL on Windows with zig cc does not produce an import library (.lib)

[alexrp]

An import library is, depressingly, still required in 2021 to link against a DLL on Windows. LLD is not yet capable of linking directly against a DLL like MinGW's linker.

Normally, when you link C code with lld-link -dll foo.obj, you'll get both foo.dll and foo.lib. This also appears to be the case with zig build-lib -dynamic. However, with zig cc -shared, this is not the case, and -Wl,-implib:foo.lib does not work either.

By the way, if anyone can point me in the right direction, I could try to put a PR together for this. I can't for the life of me figure out where Zig makes the decision to emit an import library for zig build-dll -dynamic though.
