[Boost-users] [program_options] VC6 compile error 'illegal pure syntax, must be "=0"'

Hi All,
 
I am having problems using the [program_options] library from Boost
1.33. Using this simple program:
 
#include <boost/program_options.hpp>
 
int main(int argc, char* argv[])
{
 return 0;
}
 
I get compile errors like:
 
options_description.hpp(156) : error C2258: illegal pure syntax, must be
'= 0'
options_description.hpp(156) : error C2252: 'm_default_line_length' :
pure specifier can only be specified for functions
options_description.hpp(159) : error C2065: 'm_default_line_length' :
undeclared identifier
 
This is the first time I'm using Boost. I have successfully developed a
program that uses boost::filesystem but I have funny feeling this is a
compiler limitation which means I can not use [program_options] on VC6.
 
Can anyone confirm this so I can forget about program_options?
 
Thanks!
Hennie.
