  • Remove mr_string.c|.h useless and in de=uplication with mr_str.c|.h
  • Solve with valgrind's help some memroy leak (harmless mostly)
  • Solve a seg fault at end, when unallocating a bkpinfo member after the strcuture disallocation !
  • after mr_strtok, memory ssociated with the token needs to be free
  • Adds a new function free_newt_stuff to free newt related allocated memory
  • Do not exit if mr_free is unsuccessful, and only warn when debug > 8
  • Property svn:keywords set to Id
