Subject: * process.c (security): always give warning for insecure PATH.

* dir.c (my_getcwd): do not rely on MAXPATHLEN.

* file.c (rb_file_s_readlink): ditto.

* file.c (path_check_1): ditto.

* eval.c (rb_yield_0): should not call rb_f_block_given_p().

* string.c (rb_str_chomp_bang): should terminate string by NUL.

* eval.c (rb_yield_0): better error message.
