Raw Normal View History

* Added support for X11 modules. * Makefile: change location of FORMS library. * posixmodule.c: turn #if 0 into #ifdef MSDOS (stuff in unistd.h or not) * Almost all .h files: added CPP magic to avoid duplicate inclusions and to support inclusion from C++.

#ifndef Py_MYMALLOC_H
#define Py_MYMALLOC_H
* renamed malloc.h mymalloc.h, and added MALLARG as the type of the argument to malloc() (size_t or unsigned int) * listobject.c: check for overflow of the size of the object, so things like range(0x7fffffff) will raise MemoryError instead of calling malloc() with -4 (and then crashing -- malloc's fault)

/***********************************************************
Added 1995 copyright. object.h: made sizes and refcnts signed ints. stringobject.h: make getstrsize() signed int. methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.
