[Fred L. Drake]

Update of /cvsroot/python/python/dist/src/Include
In directory slayer.i.sourceforge.net:/tmp/cvs-serv19656/Include

Modified Files:
	node.h opcode.h 
Log Message:

Charles G. Waldman <cgw@fnal.gov>:
Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit.  This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.

This closes the implementation portion of SourceForge patch #100893.
