Hi, Andrey.

The first spotted:

---
+int PASCAL wWinMain ( HINSTANCE hInstance, HINSTANCE prev, LPWSTR 
cmdline, int show )

+{
...
+    UINT    j = 0;
---

This initializer looks redundant

---
+LPWSTR* ParseCmdline( LPCWSTR cmdline, int *argc )

+    BOOL    bQuote = FALSE;

...
+    i = j = k = z = nQuotes = 0;
---

This is redundant for i and nQuotes at least.
