Fix for MoveFileExA

[Aric Stewart]

My turn to chime in, I have done a fair bit of reboot processing stuff..
first here is what msdn says

>>
If the dwFlags parameter specifies MOVEFILE_DELAY_UNTIL_REBOOT, MoveFileEx stores
the locations of the files to be renamed at reboot in the following registry
value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\PendingFileRenameOperations

The function fails if it cannot access the registry.

The PendingFileRenameOperations value is of type REG_MULTI_SZ. Each rename
operation stores a pair of NULL-terminated strings. The system uses these registry
entries to complete the operations at reboot in the same order that they were
issued. For example, the following code fragment creates registry entries that
delete szDstFile and rename szSrcFile to be szDstFile at reboot:

MoveFileEx(szDstFile, NULL, MOVEFILE_DELAY_UNTIL_REBOOT);
MoveFileEx(szSrcFile, szDstFile, MOVEFILE_DELAY_UNTIL_REBOOT);

The system stores the following entries in PendingFileRenameOperations:

szDstFile\0\0
szSrcFile\0szDstFile\0\0

Because the actual move and deletion operations specified with the
MOVEFILE_DELAY_UNTIL_REBOOT flag take place after the calling application has
ceased running, the return value cannot reflect success or failure in moving or
deleting the file. Rather, it reflects success or failure in placing the
appropriate entries into the registry.

The system deletes a directory tagged for deletion with the
MOVEFILE_DELAY_UNTIL_REBOOT flag only if it is empty. To ensure deletion of
directories, move or delete all files from the directory before attempting to
delete it. Files may be in the directory at boot time, but they must be deleted or
moved before the system can delete the directory.

Windows 95 and Windows 98: The MoveFileEx function is not supported. To rename or
delete a file at reboot, use the following procedure.

    To rename or delete a file on Windows 95 and Windows 98
Check for the existence of the WININIT.INI file in the Windows directory.
If WININIT.INI exists, open it and add new entries to the existing [rename]
section. If the file does not exist, create the file and create a [rename]
section.
Add lines of the following format to the [rename] section:
DestinationFileName=SourceFileName

Both DestinationFileName and SourceFileName must be short filenames. To delete a
file, use NUL as the value for DestinationFileName.

The system processes WININIT.INI during system boot. After WININIT.INI has been
processed, the system names it WININIT.BAK.
<<

So we have exactly what we should do.

This i have seen alot, andreas (and others) are working on a utility that will
process this wininit file. I have talked to alexandre and we both agree that it is
something that probably should not be in wine itself.
