Check for pthread_sigmask before using it. Fixes remaining problem in #470781.

Pass binary mode to makefile().

zlib.adler32() are not suitable as general hash functions.

that -Kpthread is supported. Fixes #470781.
Port to autoconf 2.52.

failobj, and when getting the subtype use 'plain' as the failobj.
text/plain is supposed to be the default if the message contains no
Content-Type: header.

Prompted by Jim Ahlstrom.  This closes SF patch #470614.

Ugly, but it works.

using the same algorithm as the slot updates.  The slotdefs array is
now sorted by slot offset and has an interned string object corresponding
to the name added to each item.  More can be done but I need to commit
this first as a working intermediate stage.

debug mode (--with-pydebug).

Remove the log file after we are done with it.  This should clean up after
the test even on Windows, since the file is now closed before we attempt
removal.

Rearranged the growing number of Lib packages into alphabetical order.

Simply commented it out, and then test_hotshot passes on Windows.
Leaving to Fred to fix "the right way" (it seems to be a feature of
unittest that all unittests try to unlink open files <wink>).

This still doesn't compile on Windows, but at least I have a shot at
fixing that now.

use 0x format for id. Proposed by Cesar Eduardo Barros in patch #470680.

   This patch changes to logic to:

   if env.var. set and non-empty:
       if env.var. is an integer:
           set flag to that integer
   if flag is zero: # [actually, <= 0 --GvR]
       set flag to 1

   Under this patch, anyone currently using
   PYTHONVERBOSE=yes will get the same output as before.

   PYTHONVERBNOSE=2 will generate more verbosity than
   before.

   The only unusual case that the following three are
   still all equivalent:
   PYTHONVERBOSE=yespleas
   PYTHONVERBOSE=1
   PYTHONVERBOSE=0

Still broken:  GETTIMEOFDAY.  This macro obviously isn't being defined
on Windows, so there's logic errors here I'd rather Fred untangled.

   This patch updates Python/thread_pthread.h to mask all
   signals for any thread created. This will keep all
   signals masked for any thread that isn't the initial
   thread. For Solaris and Linux, the two platforms I was
   able to test it on, it solves bug #465673 (pthreads
   need signal protection) and probably will solve bug
   #219772 (Interactive InterPreter+ Thread -> core dump
   at exit).

   I'd be great if this could get some testing on other
   platforms, especially HP-UX pre 11.00 and post 11.00,
   as I had to make some guesses for the DCE thread case.
   AIX is also a concern as I saw some mention of using
   sigthreadmask() as a pthread_sigmask() equivalent, but
   this patch doesn't use sigthreadmask(). I don't have
   access to AIX.

tool; look for that on Monday.

reported and can read the log back in.

up GCC warnings.

The problem is that if fread() returns a short count, we attempt
another fread() the next time through the loop, and apparently glibc
clears or ignores the eof condition so the second fread() requires
another ^D to make it see the eof condition.

According to the man page (and the C std, I hope) fread() can only
return a short count on error or eof.  I'm using that in the band-aid
solution to avoid calling fread() a second time after a short read.

Note that xreadlines() still has this problem: it calls
readlines(sizehint) until it gets a zero-length return.  Since
xreadlines() is mostly used for reading real files, I won't worry
about this until we get a bug report.
