[Bug 18089] New: import_dll should check SharedDLLs

http://bugs.winehq.org/show_bug.cgi?id=18089

Summary: import_dll should check SharedDLLs
           Product: Wine
           Version: 1.1.19
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

import_dll should lookup in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls for
matching library, if it can't find it anywhere else.

Here's how I came to this: there are lots of programs that don't start in wine
unless you do special tricks, such as copying dlls to folder where the .exe
resides or to system32, or something else. If you search the bugzilla for
import_dll, you'll find a lot of bugs having this kind of errors:

err:module:import_dll Library something.dll not found

Mostly, questions arise as if software has installed correctly or something
else. But, I've made a test, installing it in windows, and launching directly,
that is without specifying "start in" parameter (as it would with .lnk files).
And in windows it works perfectly.

So, I've exported the registry from XP box and compared it to identical
installation in wine. The only mentions of dlls in question are in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls

Google says, that this registry node is supposed only to track if installed
libraries are used by any installed application or not.

But it seems, that in windows, ntdll looks up into this registry part in order
to try to find where the libraries in question are located.

This would fix quite a lot of problems.
