Summary: Python2.4: building '_socket' extension fails with `INET_ADD

Initial Comment:
HI!

I'm trying to build Python2.4 on a rather old Debian
machine. 
Building _socket fails (see below) although I tried to use

configure --disable-ipv6

I've added

#define INET_ADDRSTRLEN 16

to Modules/socketmodule.h which made it work. There
were no problems compiling Python2.2 on the very same
machine.

Ciao, Michael.

Unfortunately, non of us has Solaris 7, so there is little
chance that we are able to develop a patch. Can you provide one?

My users then see...

# regtester.py ../ini/tester.ini main

I try your work-around.  Doesn't help.

There are already a few attempts to define ADDRSTRLEN if it
is missing. Maybe we should just merge them into one, and
define it if it is not defined, independent of the system.

How old a debian release is this? It sounds like it's a just
a broken system header, and I'm not entirely convinced that
adding this to the already-large collection of #ifdefs in
socketmodule is a path to happiness.
