Believe it or not, Solaris 2.6 strtod() can move the end pointer
*beyond* the null byte at the end of the input string, when the input
is inf(inity). Discovered by Greg Ward.
On second though, NEXITFUNCS should be defined in pythonrun.c and not
here; pystate.h doesn't use it (I thought I wanted to move the array
there but that won't work).

While scalling sys.modules, skip entries that don't have string keys,
to protect us from jokers who put items with non-string keys in
sys.modules. Reported by Greg Stein.
Fix suggested by Sjoerd (long ago!) to get a better error message when
there's a syntax error. (In particular, display the correct
filename). This changes the API: if there's a syntax error, the
function now returns normally after dumping the error to sys.stderr.
I changed Sjoerd's use of string.join(string.split(...)) with
string.replace().
Added a debug function to replace 'print' statements.
Ensured that response attached to 'NO' replies is passed back.
added readonly exception.
Rearranged method order into types.
Ensure select returns a meaningful error on 'NO'.
'NO' returns from authenticate and login raise error with last message,
not list.
1. Generate a correct Content-Length header visible through the info() method
if a request to open an FTP URL gets a length in the response to RETR.
2. Take a third argument to urlretrieve() that makes it possible to progress-
meter an urlretrieve call (this is what I needed the above change for).
See the second patch band below for details.
3. To avoid spurious errors, I commented out the gopher test. The target
document no longer exists.

(py-execute-file, py-execute-import-or-reload): Use a Python `raw'
string in the argument to execfile() so a Windows temp directory
named, e.g. c:\\tmp doesn't get interpreted as a file name with an
embedded tab! (given by C. Waldman).
Reworked it quite a bit. There are now two classes: a base class,
InteractiveInterpreter, which handles parsing and interpreter state
but doesn't know deal with buffering or prompting or input file
naming. And a derived class, InteractiveConsole, which adds buffering
and prompting and supports setting the filename once. Also tweak the
algorithm in compile_command() a bit so that input consisting of all
blank lines or comments always succeeds immediately, and note the fact
that apart from SyntaxError it can also raise OverflowError.
Do the check for lacking sys.stdin.fileno() *before* testing for
Windows. If sys.stdin doesn't appear to be a real file (characterized
by having a working fileno()), don't use any console specific methods
-- go straight to the default.
Get rid of the classes RModuleLoader and RModuleImporter -- these were
only there to override reload() in a way that doesn't make a whole lot
of sense and moreover broke since the latest changes in ihooks.
Comment out 't = t[0] + t[1]' in profiler_simulation() -- this
function is only used when running the calibration code, and it turns
out that recent changes in the timing code caused this statement to
raise an exception.
Patches from Greg Stein to support 'P' format in struct module's
native format, as void* (translated to Python int or long).
Also adds PyLong_FromVoidPtr and PyLong_AsVoidPtr to longobject.c.
In load_inst(), when instantiating an instance the old way (i.e. when
there's an __getinitargs__() method), if a TypeError occurs, catch and
reraise it but add info to the error about the class name being
instantiated. This makes debugging a lot easier if __getinitargs__()
returns something bogus (e.g. a string instead of a singleton tuple).
Ignore the TclError exception raised when deleting the registration
for callit, used by the after() command. This can happen when the
callback deletes the window.

Several changes that Python carry on in the face of errors in the
initialization of class exceptions. Specifically:
init_class_exc(): This function now returns an integer status of the
class exception initialization. No fatal errors in this method now.
Also, use PySys_WriteStderr() when writing error messages. When an
error occurs in this function, 0 is returned, but the partial creation
of the exception classes is not undone (this happens elsewhere).
Things that could trigger the fallback:
- exceptions.py fails to be imported (due to syntax error, etc.)
- one of the exception classes is missing (e.g. due to library
version mismatch)
- exception class can't be inserted into __builtin__'s dictionary
- MemoryError instance can't be pre-allocated
- some other PyErr_Occurred
newstdexception(): Changed the error message. This is still a fatal
error because if the string based exceptions can't be created, we
really can't continue.
initerrors(): Be sure to xdecref the .exc field, which might be
non-NULL if class exceptions init was aborted.
_PyBuiltin_Init_2(): If class exception init fails, print a warning
message and reinstate the string based exceptions.
