That works. Hacking configure so it looks like the following
allows python to build:
case $ac_sys_system/$ac_sys_release in
# On OpenBSD, select(2) is not available if
_XOPEN_SOURCE is defined,
# even though select is a POSIX function. Reported by J.
Ribbens.

Yes, _POSIX_C_SOURCE is defined as 200112L; together with
_XOPEN_SOURCE (600) and _XOPEN_SOURCE_EXTENDED (1).
Can you please locate the block that sets
define_xopen_source in configure and see whether setting
this to no helps?
It looks to me that Solaris 2.6 is quite broken in this
respect, but I would accept adding it to the list of
known-broken systems, along with a comment that explains how
precisely it breaks.

Lots (possibly all) of the HAVE_*_H tests in configure are
failing:
In file included from /usr/include/sys/wait.h:25,
from /usr/include/stdlib.h:22,
from configure:2876:
/usr/include/sys/siginfo.h:204: field `__value' has
incomplete type
I think the offending bits of code in sys/siginfo.h are:
#if (!defined(_POSIX_C_SOURCE) && !defined(_XPG4_2)) || \
(_POSIX_C_SOURCE > 2) || defined(__EXTENSIONS__)
union sigval {
int sival_int; /* integer value */
void *sival_ptr; /* pointer value */
};
#else /* needed in siginfo_t
structure */
union __sigval {
int __sival_int; /* integer value */
void *__sival_ptr; /* pointer value */
};
#endif
[...]
#if !defined(_XPG4_2) || defined(__EXTENSIONS__)
union sigval __value;
#else
union __sigval __value;
#endif
Would _POSIX_C_SOURCE be getting set to a value > 2, which
would break siginfo.h?
PS. This Solaris 2.6 machine isn't mine and I can't give
access to it.

This gets more and more confusing. Include/Python.h does
include both <unistd.h> and <stdlib.h>. Can you find out why
it isn't included on your system?

Adding a #include <unistd.h> Fixes the following:
./Modules/posixmodule.c: In function `posix_fchdir':
./Modules/posixmodule.c:1200: `fchdir' undeclared (first use
in this function)
./Modules/posixmodule.c:1200: (Each undeclared identifier is
reported only once
./Modules/posixmodule.c:1200: for each function it appears in.)

./Modules/posixmodule.c: In function `posix_fsync':

in this function)
./Modules/posixmodule.c: In function `posix_fdatasync':
./Modules/posixmodule.c:1267: `fdatasync' undeclared (first
use in this function
Adding #include <stdlib.h> fixes the following:
./Modules/posixmodule.c: In function `posix_system':
./Modules/posixmodule.c:1868: warning: implicit declaration
of function `system'
./Modules/posixmodule.c: In function `posix_execv':

./Modules/posixmodule.c: In function `posix_tempnam':
./Modules/posixmodule.c:5917: warning: implicit declaration

./Modules/posixmodule.c: In function `setup_confname_table':
./Modules/posixmodule.c:6903: warning: implicit declaration

Changing line 187 from:
extern char *getcwd(char *, int);
to:
extern char *getcwd(char *, size_t);
And everything builds happily.

I find several things confusing in this report:
- why is va_list redefined? To my knowledge, gcc 2.95.2
supports Solaris 2.6 correctly, so it shouldn't provide a
conflicting va_list definition. The typical cause is that
the gcc installation doesn't match the operating system
version (i.e. fixincludes was run for different headers).
Since the gcc installation appears to have been built for
2.6, I infer that the system being used might not be Solaris
2.6.
- All the problems reported are warnings, which don't cause
compilation to fail. What is the actual error (use -w to
suppress all warnings).

Jeff, I don't know if anyone has access to Solaris 5.6. Can
you provide a patch to get posixmodule to compile? From the
bug report, I only see warnings, not an actual error which
is breaking the build.
