I just played around with Thandor trying to install it and see what the differences are between Win98 and Wine because I noticed a slightly different behaviour. Now I discovered that MoveFileEx is not even available in Windows 98 but wine supplies it nevertheless. I suspect that the Setup doesn't check the windows version, but rather calls MoveFileEx and if that fails with not implemented returncode continues with other code to supply the functionality. I wrote a small test app to confirm this and this returns an error code when calling MoveFileEx on a native win98 whiel wine executes it.
How shall I fix this? Shall I simply call GetVersion() to determine if MoveFileEx should be allowed or is there a different way with wine to determine which functions are available for which version (a global variable or such)? I looked through the sources but I couldn't find anywhere something where a versioncheck has been used to switch code but then again I don't know much functions where I know for sure that they are available in one version and not in the other.
Why is it a problem? There is no guarantee Wine will be run with the same --winver next time, so the "boot" utility or startup code has to handle both idiotic mechanisms. It is not important to _me_ that Wine should be exactly as Windows, only that it should work well.
If an app that people find useful refuses to work at all if it finds functions that it thinks should not be there, I guess we might have to cater for it, but I'd rather not.
