    realpath(3): Upgrade to POSIX IEEE Std 1003.1-2008
    
    Recent updates to realpath implements some of the missing POSIX
    functionality, but the requirement to allocate memory for the pointer
    returned by the function when a null pointer is passed to the
    resolved_path argument was missing.
    
    The prototype changes in the following ways:
    1.  The restrict type qualifier is added to both arguments
    2.  The second argument changes from "char resolved[PATH_MAX]" to
        "char * resolved"
    
    The new prototype is backwards-compatible with the old one.
    
    This should bring realpath up to Open Group Specifications Issue 7
    IEEE Std 1003.1-2008
