[Python-checkins] python/dist/src/Include compile.h, 2.37.2.8, 2.37.2.9

[nascheme at users.sourceforge.net]

Update of /cvsroot/python/python/dist/src/Include
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20689/Include

Modified Files:
      Tag: ast-branch
	compile.h 
Log Message:
Implement a smarter stackdepth() function.

  * Move 'instr' and 'basicblock' structure definitions out of compile.h
    and into newcompile.c.

  * Add an 'i_target' field to the 'instr' struct.  Use it instead of
    using 'i_oparg' for both block indices and instruction offsets.

  * Update list of outstanding issues and bugs.
