The great renaming, phase two: all header files have been updated to use the new names exclusively, and the linker will see the new names. Files that import "Python.h" also only see the new names. Files that import "allobjects.h" will continue to be able to use the old names, due to the inclusion (in allobjects.h) of "rename2.h". 1995-01-12 12:45:45 +01:00			`PyFloatObject represents a (double precision) floating point number.`

Add cast to PyFloat_AS_DOUBLE macro, as suggested by Marc Lemburg. 1997-08-02 04:40:58 +02:00			`#define PyFloat_AS_DOUBLE(op) (((PyFloatObject *)(op))->ob_fval)`
* 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++. 1993-07-28 11:05:47 +02:00
