i would first try to use the default getopt_long and alloca installed on
the system, and then, if they aren't supported by the system, fall back to
the implementation provided with nc6.

i have seen that you did this with alloca, but your code seems to make
always use of the getopt_long function supplied with nc6. is there a
particular reason (maybe a bad portability for getopt_long on non-linux
systems?) for this?

very good! :-)
