> it doesn't matter if our v5 has manifest or not. I think we don't have to care about that at this point. Yeah. We don't need to care about whether comctl32 v5 has a manifest or not at this point. The problem with this part of the code is that comctl32 v6 doesn't get some of its window class version from its manifest without this change. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8595#note_110490

First, we need to pack variable-length data into e_lfanew for every DLL/EXE(output_pe_file(),output_module16, etc). Then we need to change this signature parsing to support variable-length data(winedump, dbghelp, build_module() in NTDLL, ntdll DLL loader, setupapi fakedll support). There will probably be alignment issues to be handled. Also, increasing e_lfanew might increase the chance of anti-virus software misdetecting wine DLLs as malware. Overall, I don't think it's worth it to extend the built-in signature check for this. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8595#note_110489

> Is there an embedded manifest in comctl32.dll from system32? No. The manifest seems to be from somewhere else. Anyway, I think it's clearer that the manifest is for comctl32 v6 this way. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8595#note_110485

Another way would be to extend this builtin signature check to optionally include installed module name instead of assuming it's the same as a filename, so that we can specify comctl32_v6.dll there and build everything as builtin. I don't know if it's easy, because it requires variable length data. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8595#note_110484

However, we need to mark comctl32 v5 as --perfer-native because comctl32.dll in the build dir is comctl32 v5. Then we still need to update the wine prefix every time after making changes to comctl32 v6 and rebuilding, because otherwise the comctl32 v6 DLL in the wine prefix won't be updated, now that the DLL in the wine prefix is preferred. This would make the comctl32 development worse. Comparing it to a special case in find_builtin_dll(), I prefer the latter.

So unless application requests specific 5.x version (if that's really the purpose of having this manifest) it doesn't matter if our v5 has manifest or not. I think we don't have to care about that at this point. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8595#note_110481
