Really check success of getcwd(3)

Browse Source 
`getcwd(3)' returns a NULL pointer when it fails, and a pointer to the buffer
when it succeeds. The array of characters (allocated on the stack) is not NULL,
so it cannot be used to check if `getcwd(3)' succeeded. Use the pointer
returned by `getcwd(3)' to check success.
