     Type:  Bugs                     |      Status:  new    
Milestone:  Boost 1.43.0             |   Component:  GIL    
  Version:  Boost 1.42.0             |    Severity:  Problem
 Keywords:                           |  
-------------------------------------+--------------------------------------
 libpng version 1.4.0 (up from 1.2.40) removes several macros such as the
 following:

 #define png_infopp_NULL           NULL

 Which GIL was using.


 Fix:
 Replacing the symbols png_infopp_NULL and int_p_NULL with NULL in the
 files boost/gil/extension/io/png_io_private.hpp and
 boost/gil/extension/io/png_dynamic_io.hpp seems to fix the problem.

 Note: I have only compiled, I have not actually used the functions which
 use these symbols.
