PVS-Studio warning V532 for FCEUX

void splitpath(const char* path, char* drv, char* dir,
               char* name, char* ext)
{
  const char* end; /* end of processed string */
  const char* p;  /* search pointer */
  const char* s;  /* copy pointer */
  ...
  for(s=p; s<end; )
    *s++;
  ...
}

I cannot understand at all what the programmer wanted to do here. This code is equivalent to s = end.

This suspicious code was found in FCEUX project by PVS-Studio static code analyzer.
Warning message is:
V532 Consider inspecting  the statement of '*pointer++' pattern. Probably meant: '(*pointer)++'. fceux xstring.cpp 444
