Generate Carbon as well as classic PPC plugin projects. This module is finally paying back the investment in it!

Fixes bug #121706.

Added Matthias Neeracher and Alexandre Parenteau to the "thank you" list. This should have been done _ages_ ago for Matthias! Shame shame!!

Upped the default memory size to a whopping 24Mb, which is needed to make the autotests run. Sigh. User with low-memory systems will have to adapt the setting.

Py_Initialize()/Py_Finalize() loop leaks.

- allow an optional 3rd argument which is the loop count.  -1 means
  infloop (the default).

- Add a setting of Py_NoSiteFlag=1, but leave it commented out by
  default.

- set VERSION to 2.1

- change blddir to ../.. since that seems more common than the old
  value (at least for my debugging session).

WITH_CYCLE_GC.

PyGC_Dump(): Wrap this in a #ifdef WITH_CYCLE_GC.

pull it in automatically.

PyObject_Dump(): New function that is useful when debugging Python's C
runtime.  In something like gdb it can be a pain to get some useful
information out of PyObject*'s.  This function prints the str() of the
object to stderr, along with the object's refcount and hex address.

PyGC_Dump(): Similar to PyObject_Dump() but knows how to cast from the
garbage collector prefix back to the PyObject* structure.

[See Misc/gdbinit for some useful gdb hooks]

none_dealloc(): Rather than SEGV if we accidentally decref None out of
existance, we assign None's and NotImplemented's destructor slot to
this function, which just calls abort().

module__doc__: Document the Warning subclass heirarchy.

make_class(): Added a "goto finally" so that if populate_methods()
fails, the return status will be -1 (failure) instead of 0 (success).

fini_exceptions(): When decref'ing the static pointers to the
exception classes, clear out their dictionaries too.  This breaks a
cycle from class->dict->method->class and allows the classes with
unbound methods to be reclaimed.  This plugs a large memory leak in a
common Py_Initialize()/dosomething/Py_Finalize() loop.

sources. So far only runs under unix, but what gives:-)

fixed typo in ihooks docstring

complaints.  The new version moves most of its initialization to
package load time; it's simpler, faster, smaller, and adds support for
Mozilla and Links.  Interpretation of the BROWSER variable now works
and is documented.  The open_new entry point and methods are marked
"deprecated; may be removed in 2.1".

don't fail if they're not available.

the previous auto-configuring modules feature (already obsolete :-).

Grammatical and typographic fixes from David Goodger
Expanded notes about PEP 229
Removed user-visible XXXes; they're in comments now

by weird and (hopefully) unnecessary SET_CXX and SET_DLLLIBRARY macros
that occurr at the start of Makefile.in files.

- Also removed the already-commented-out SET_CCC macro cruft.
