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 19:45:45 +08:00			`PyFloatObject represents a (double precision) floating point number.`
