Sergio Durigan Junior 43573013c9 Get rid of "gdb_dirbuf" and use "getcwd (NULL, 0)" ... Currently we have "current_directory" and "gdb_dirbuf" globals, which means that we basically have two possible places to consult when we want to know GDB's current working directory. This is not ideal and can lead to confusion. Moreover, the way we're using "gdb_difbuf" along with "getcwd" is problematic because we declare the buffer with "1024" elements hardcoded, which does not take into account longer pathnames that are possible in many filesystems. Using "PATH_MAX" would also not be a solution because of portability problems. Therefore, the best solution is to rely on the fact that "getcwd (NULL, 0)" will "do the right thing" and return a heap-allocated string containing the full path. With the new "getcwd" module from gnulib, it is now possible to do that without worrying about breaking some host. With this patch "current_directory" is now the only place to check for GDB's cwd.
