e8a0788b24 moved biggest stack buffers to malloc space, or made their size configurable
(8k of shell line edit buffer is an overkill)

77e44d60e6 httpd: move data off bss.
httpd: do not realpath() for SCRIPT_FILENAME - it resolves symlinks
but it should not:

-                /* SCRIPT_FILENAME required by PHP in CGI mode */
-               if (!realpath(purl + 1, realpath_buff))
-                       goto error_execing_cgi;
-               setenv1("SCRIPT_FILENAME", realpath_buff);
+
+               /* SCRIPT_FILENAME required by PHP in CGI mode */
+               fullpath = concat_path_file(home_httpd, purl);
+               setenv1("SCRIPT_FILENAME", fullpath);

bb4b9f1fc9 - add a config-time range check for IPC_SYSLOG_BUFFER_SIZE
The upper-bound doesn't look like it is working since it accepts LONG_MAX as input. I suspect that this is an lxdialog feature or something like that ;)
