Update of /projects/cvsroot/python/dist/src/Python
In directory eric:/projects/python/develop/guido/src/Python
Modified Files:
	bltinmodule.c 
Log Message:
Patch by Jim Fulton (code style tweaked a bit) to support
ExtensionClasses in isinstance() and issubclass().
 - abstract instance and class protocols are used *only* in those
 cases that would generate errors before the patch. That is, there's
 no penalty for the normal case.
 - instance protocol: an object smells like an instance if it 
 has a __class__ attribute that smells like a class.
 - class protocol: an object smells like a class if it has a 
 __bases__ attribute that is a tuple with elements that
 smell like classes (although not all elements may actually get
 sniffed ;).
