If your app is looking for system dll's with, say, CreateFile you have
to put a file there for it to find, in whatever unix directory you have
told wine is "System".  Consider my expurgated .wine/config:

WINE REGISTRY Version 2

[Drive C]
"Path" = "/gp/windose"
"Type" = "hd"
"Label" = "/gp/windose"
"Filesystem" = "win95"

[wine]
"Windows" = "C:\\windows"
"System" = "C:\\windows\\system"
"Temp" = "e:"
"Path" = "C:\\windows;c:\\windows\\system;e:\\;c:\\Program Files;j:\\lccpub\\bin"
"Profile" = "c:\\windows\\Profiles\\Administrator"
"GraphicsDriver" = "x11drv"

# <wineconf>


[DllOverrides]
"msvcrt"       = "native, builtin, so"
"*"            = "builtin, so, native"

[AppDefaults\\juno.exe\\DllOverrides]
"msvcrt"       = "native"
"riched32"     = "native"

[AppDefaults\\netscape.exe\\DllOverrides]
"msvcrt"       = "native"

I could make a nice advapi32.dll this way:

touch /gp/windose/windows/system/advapi32.dll

When the app goes after a dll with LoadLibrary of GetFileVersion.. it
gets what the Wine administrator tells Wine it should use.

Notice the [DllOverrides].

Wine has a large collection of builtin dll's.  Depending what --prefix
wine was configured with (default is /usr/local), builtin dlls are in

${prefix}/lib

and are named libkernel32.so, libntdll.so, and so on.  Indeed Wine can
not use windows kernel, user, ntdll, or gdi.  If you tell it to, the
best you can hope for is a nice clean crash.  I recommend you use no
native windows dll's except msvcrt, unless your app insists.  Mine won't
run without native riched32.dll.
