Prevent the lengths passed to PyString_FromStringAndSize()
from being negative in some cases.

Correct source of *strip() changes
Small rewrites.

customize_compiler() now looks at various environment variables and uses
   their values to override the configured C compiler/preprocessor/linker
   binary and flags.

Fixed the signed/unsigned confusions when dealing with files >= 2GB.
4GB is still a hard limitation of the gzip file format, though.

Testing this was a bitch on Win98SE due to frequent system freezes.  It
didn't freeze while running gzip, it kept freezing while trying to *create*
a > 2GB test file!  This wasn't Python's doing.  I don't know of a
reasonable way to test this functionality in regrtest.py, so I'm not
checking in a test case (a test case would necessarily require creating
a 2GB+ file first, using gzip to zip it, using gzip to unzip it again,
and then compare before-and-after; so >4GB free space would be required,
and a loooong time; I did all this "by hand" once).

Bugfix candidate, I guess.

\@makefntext than \@footnotetext, so we'll do that instead.

   when output is redirected to a file, compiler error messages show
   up before Distutils prints the command being invoked.

   whether the Distutils being used supports a particularly capability.

   (This idea was originally suggested by Juergen Hermann as a method
    on the Distribution class.  I think it makes more sense as a
    function in core.py, and that's what this patch implements.)

The @euro part is backported to 2.2.3.

Try to write to TESTFN, if that fails, try TESTFN in /tmp
If that fails, print a warning and go on.
Will backport.

Will backport.

Redo setting the selection and setting the beacon to deal better
with rows or columns -- these are now expressed by range (1, sys.maxint).

Joseph Winston recommends removing DYNAMIC_PATH, since it can
cause some dynamic libraries to not load on HP-UX 11.

Cast param to isalnum() to int.

On HPUX, Solaris, Tru64 (Dec UNIX), and IRIX (I think),
O_NONBLOCK is the POSIX version of non-blocking I/O
which is what we want.

On Linux and FreeBSD (at least), O_NONBLOCK and O_NDELAY are the same.
So this change should have no negative effect on those platforms.

Tested on Linux, Solaris, HPUX.

Thanks to Anders Qvist for diagnosing this problem.

Cleanup (remove) the file(s) after we are done with the test.
(Fixes problem on snake farm)

Return PyLongs instead ot PyInts.
On alphas, 9223372036854775807 became -1.

works.  Also row and column selection works (sort of).  The DEL
key deletes the selected rectangle.  sys.argv[1] used by test_gui().

preference of using "is" instead of "==" to compare types, use
built-in names where available, and point to the isinstance()
function.
Closes SF bug #632196.
