Your patch looks wrong to me. Looking at the definitions of wthePath and 
wtheRealPath, these variables are wide character strings. So you must not use 
the standard string functions strncpy and strncat to copy and modify these 
variables, but instead you should use their wide character variants wcsncpy and 
wcsncat.
