Summary: socketmodule won't compile on BSDI 4.0
Initial Comment:
Trying to build 2.2b2 on BSDI BSD/OS 4.0 with gcc
2.7.2.1 and gcc 2.95.2, and the socket module won't
build. No problems building socket for Python 2.1.1
on this same machine.
% ./configure --with-threads=no
# for socket(2), without SSL support.
_socket socketmodule.c
% gmake

Arrghh. I was trying to find out which of the tests fail,
but attached the wrong version of the file: I meant to put
printfs into each failure. Please try aicheck2.c instead.
Anyway, it seems that your system is indeed one of those
where the test should find out problems with the C library
(unless the test that fails is bogus, which we can
investigate once we know what it is that fails). I'll try to
come up with a patch that allows usage of the getaddrinfo
emulation even on systems where getaddrinfo is in the C library.

aicheck.c compiled without problem on my system.
% gcc -o aicheck aicheck.c
%
Running the resulting binary produces no output. I'm
not exactly sure what kind of output you are looking for
(taking a guess):
% gdb /home/jason/temp/aicheck

Thansk for the files. I now trying to figure out why Python
refuses to use the getaddrinfo implementation in your C
library. It may be that it is really broken, in which case
we must make getaddrinfo.c work correctly. Perhaps it ought
to work,and configure just fails to correctly see that.
So please compile the attached file aicheck.c on your
system, and report output and status code (looking at $?);
if it fails to compile, report the compile errors.

Attached are three files:
- pyconfig.h from a fresh gcc 2.7.2.1 build
- config.log from a fresh gcc 2.7.2.1 build
- /usr/include/netdb.h
- the getaddrinfo manual page from my system
Indeed, EAI_ADDRFAMILY is defined in /usr/include/netdb.h,
but EAI_MAX is not. Let me know if I can provide any more
information. Thanks.

Ok, then we need to investigate the configure results. Can
you please attach pyconfig.h and config.log to this report?
Also, can you please confirm that you build Python from
scratch with 2.7.2.1 (i.e untarring a fresh source tree, to
avoid using a config.cache left over from gcc 2.95.2)?
Furthermore, can you please report details of the
getaddrinfo implementation on your system? Does it provide
one? In the C library? If not, can you confirm that
EAI_ADDRFAMILY is defined in your system headers, but
EAI_MAX is not? If yes, can you speculate as to why
configure thinks your system does not have getaddrinfo?

I probably should have included the output from gcc 2.7.2.1
instead which I know is properly installed. The results are
similar, although there is no mention of `wint_t':

Are you sure the compiler is properly installed? That you
have wint_t definition both in wchar.h and stddef.h (as
fixincluded by gcc) is not Python's doing; either the header
files of your operating system are corrupt, or the compiler
is broken.
If you cannot figure out the details, please attach both
header files to this report.
