  • Another round of strcpy suppressions
  • find_home_of_exe() now allocates memory which has to be freed by the caller
  • Supress useless sz_last_suffix()
  • mr_getline now has the same interface as the other mr_mem functions
  • valgrind and compiler warnings fixes
  • Property svn:keywords set to Id
