  - Remove Pike from package description and from configure flags
  - drop "--without-mzscheme", we don't have it in our build-depends
  - use php-config5
  - Clean Runtime/ as well.
  - debian/rules (clean): Remove Lib/ocaml/swigp4.ml.

From SWIG 1.3.37 we deprecated all SWIG symbols that start with Py,
 
4
since they are inappropriate and discouraged in Python documentation
 
5
(from http://www.python.org/doc/2.5.2/api/includes.html):
 
6
 
 
7
"All user visible names defined by Python.h (except those defined by the included
 
8
standard headers) have one of the prefixes "Py" or "_Py". Names beginning with
 
9
"_Py" are for internal use by the Python implementation and should not be used
 
10
by extension writers. Structure member names do not have a reserved prefix.
 
11
 
 
12
Important: user code should never define names that begin with "Py" or "_Py".
 
13
This confuses the reader, and jeopardizes the portability of the user code to
 
14
future Python versions, which may define additional names beginning with one
 
15
of these prefixes."
 
16
 
 
17
This file is a simple script used for change all of these symbols, for user code
 
18
or SWIG itself.
