[Bug 12076] New: Database app refused to install unless system32/drivers/ etc/{services,host} exist

http://bugs.winehq.org/show_bug.cgi?id=12076

Summary: Database app refused to install unless
                    system32/drivers/etc/{services,host} exist
           Product: Wine
           Version: CVS/GIT
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: Installer
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

A user's informix-based app refused to install until
the empty files c:/windows/system32/drivers/etc/{services,host}
were created, see

http://winehq.org/pipermail/wine-users/2008-March/030256.html

I looked around a bit for other system32/drivers/etc files.

http://support.microsoft.com/kb/130024 describes hosts, services, and protocols
http://support.microsoft.com/kb/105997 describes lmhosts

It looks like some apps find that directory by looking at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath 
and MSN Messenger 7.5 f*cks up by changing that variable's type, see
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6343068

Getting this all right would be a lot of work.  Just creating
two empty files might be reasonable, though, since it
allows the user's app to install.
