Bug [1] is due to the fact that ntop #defines free to something that
require an l-value as an argument, just as Jan Safranek states.
Further, #defining any name reserved by the standard means the program
is out in undefined behaviour-land and deserve what it get, i.e. ntop
isn't written in C but in something else and thus can't expect to
interface cleanly with C libraries.
This can also be expressed as follows:
9899:1999 7.1.3 Reserved identifiers §1-2
...
-- Each identifier with file scope listed in any of the following
subclauses (including the future library directions) is reserved
for use as a macro name and as an identifier with file scope in
the same name space if any of its associated headers is
included.
No other identifiers are reserved. If the program declares or defines an
identifier in a context in which it is reserved (other than as allowed
by 7.1.4), or defines a reserved identifier as a macro name, the
behavior is undefined.
Fix your code!

As for comment #117 in [2], please see above.
