While I didn't write the code, the two files look like they are used
for debugging purposes.  A FILE* is created for each file (one in
ftpc.cc and one in ftps.cc) that is used in a commented-out fprintf
statement.

Since the FILE* is not used in either file currently, you can apply a
short term fix by changing the initialization of static member
variables fp_ in each file from
	FILE* <classname>::fp_ = fopen(...);
to
	FILE* <classname>::fp_ = NULL;

It isn't very elegant, and could be a problem if the fprintf
statments are ever uncommented.  Slightly more elegant approach
follows

/*  added at the top of ftps.cc and ftpc.cc  */
#define DEBUGoff

/*  replace static variable initialization line with following   */
/*  have to do this in both ftps.cc and ftpc.cc                  */
#ifdef DEBUG
  FILE* <classname>::fp_ = fopen(...);
#else
  FILE* <classname>::fp_ = NULL;
#endif

/*  uncomment the fprintf statements, then bracket with  */
/*  again, in both ftpc.cc and ftps.cc                   */
#ifdef DEBUG
  fprintf(...);  /*  this is the uncommented fprintf  */
#endif

DEBUG might not be the best choice for this macro variable.  If the
author/maintainer wants to chime in with a better name .... :)
