* filesys.c (scm_directory_p): new procedure "directory?" Returns
a boolean indicating whether its argument is a directory
port as returned by opendir (thanks to Dirk Herrmann for the

* gdbint.c (gdb_print, gdb_read): call scm_truncate_file.
* ports.c (scm_truncate_file): renamed from scm_ftruncate.
