 Hi,

 When using boost-1.49.0 with libpng-1.5.9 I also get this:
 {{{
 /xxxxx/w/slc5_amd64_gcc461/external/boost/1.49.0/include/boost/gil/extension/io/png_io_private.hpp:
 I
 n member function 'void
 boost::gil::detail::png_reader_color_convert<CC>::apply(const View&)':
 /xxxxx/w/slc5_amd64_gcc461/external/boost/1.49.0/include/boost/gil/extension/io/png_io_private.hpp:22
 8:22: error: 'int_p_NULL' was not declared in this scope
 }}}

 Grepping the boost tree also finds other occurrences:
 {{{

 Could you please confirm that the change {{{png_infopp_NULL|int_p_NULL}}}
 to {{{NULL}}} would fix the problem?

 Cheers,
