Summary: Compile of _socket fails on 2.4
Initial Comment:
I'm attempting to install Python 2.4 on an SGI Origin
2400 running Irix 6.5.22. I'm using gcc (3.3) to
compile, and I've tried using three different make
programs (make, smake, and gmake[3.80]) but get the
same error during compilation during the building of
_socket. There was not a problem building 2.2.1 on
this machine before, we never built 2.3 so I do not
know if the same problem existed. Here is the relevant
entry from the make:

Okay, I tried compiling using the Irix Mips compilers. To
do this I did a ./configure --without-gcc. However when
attempting to make it errored out. Here is the last section
of the make output:

The patch is relatively the same as the hack I tried
earlier, and noted in a follow-up. But as pointed out
test_socketserver doesn't work ("Use of the `network'
resource not enabled") and _locale doesn't work ("***

I'm not sure what else to try in order to get this working.

Some additional observations:
socketmodule.c compiles with gcc 3.3 under IRIX 6.5.21 after
applying this simple-minded patch (relative to Python 2.4):

This test works OK:

But this one doesn't:
./python Lib/test/test_socketserver.py

FWIW: socketmodule.c included in Python 2.3.4 also fails to
compile with gcc. Platform: IRIX 6.5.21, gcc 3.3 from SGI's
freeware distribution.

Martin v. Loewis asked me to take a look (because of my
involvement in http://python.org/sf/728330).
I never use gcc under IRIX. Python 2.4 works just fine with
the native IRIX compilers.
Suggestion to A. Stocker: try to modify the ifdef's in
socketmodule.c to do the right thing for gcc 3.3. I can test
your patch on our machines to make sure compilation with the
native compilers is still OK.

All,
I decided to force the issue a bit. Looking through
socketmodule.c I noticed that there was an SGI specific
check that basically disabled loading the addrinfo.h file,
which is where NI_NUMERICHOST is defined. So I put the
#define statement from the addrinfo.h file directly in the
socketmodule.c file and the compilation with _socket worked.
However this seems to be a clunky way to deal with the
situation. Plus I don't know if there's anything else like
this biting me in the butt (for instance '_locale' doesn't
compile either.)
