Last change on this file since 2304 was 2304, checked in by Bruno Cornec, 15 years ago
  • popup_and_get_string needs an allocated buffer for the moment so fixing the calls with dyn. ones
  • Fix a bug in mem.c for mr_strcat, which wasn't modifying the right pointer level
  • Property svn:keywords set to Id
