this code is only used if WITHOUT_COMPLEX is *not* defined, which is the
common case for Python builds.]
This code is actually not used unless WITHOUT_COMPLEX is defined.
However, there was no error checking that PyFloat_FromDouble returned
a valid pointer. I believe this change is correct as it seemed
to follow other code in the area.

v2 can be NULL if exception2 is NULL. I don't think that condition can happen,
but I'm not sure it can't either. Now the code will protect against either
being NULL.
cpathname could be NULL if it was longer than MAXPATHLEN. Don't try
to write the .pyc to NULL.
Check results of PyList_GetItem() and PyModule_GetDict() are not NULL.

* unified the way intobject, longobject and mystrtoul handle
values around -sys.maxint-1.
* in general, trying to entierely avoid overflows in any computation
involving signed ints or longs is extremely involved. Fixed a few
simple cases where a compiler might be too clever (but that's all
guesswork).
* more overflow checks against bad data in marshal.c.
Handle more mem alloc issues found with failmalloc
[The other half of this patch affected Python/symtable.c, and wasn't
relevant for the 2.4 branch. --amk]
Define MAXPATHLEN to be at least PATH_MAX, if that's defined. Python uses
MAXPATHLEN-sized buffers for various output-buffers (like to realpath()),
and that's correct on BSD platforms, but not Linux (which uses PATH_MAX, and
does not define MAXPATHLEN.) Cursory googling suggests Linux is following a
newer standard than BSD, but in cases like this, who knows. Using the
greater of PATH_MAX and 1024 as a fallback for MAXPATHLEN seems to be the
most portable solution.
