I run the following program and LastError is not overwritten.
But, LastError is overwritten if any error is happened.
At least, calling lstrcpynAtoW and lstrcpynWtoA with
insufficient buffer seems to cause this problem and should be fixed.

int main()
{
DWORD dwErr;
INT len;
SetLastError(0);
len = lstrlenAtoW( "foo" );
dwErr = GetLastError();
printf( "%d %08x\n", len, dwErr );
return 0;
}
the output is:
3 00000000
