That is because I happened to be perusing both lists at the time, that
is not that common.  :)

I compiled your example in Visual Studio 2005, and got these errors:
1>s:\tmp\testing\parser\spirit_testing\main.cpp(5) : error C2039:
'ascii' : is not a member of 'boost::spirit::qi'

'ascii' : is not a class or namespace name
1>s:\tmp\testing\parser\spirit_testing\main.cpp(16) : error C2065:
'blank' : undeclared identifier

First of all, ascii is not in qi, it is in spirit, so I fix that and
change your _TCHAR to just char and _tmain to just main (you are not
including windows.h after all) and change parse to phrase_parse (since
you are using a skipper, use just parse if you are not using a
skipper, basically do like my above example shown) and it compiles and
runs fine here and does stuff i with 123.
This was the fixed code:

#include <boost\algorithm\string.hpp>
#include <boost\spirit\include\qi.hpp>

namespace qi    = boost::spirit::qi;
namespace ascii = boost::spirit::ascii;

int _tmain(int argc, char* argv[])
{
        std::string number( "123" );

        int i;
        qi::phrase_parse( number.begin()
                , number.end()
                , qi::int_
                , ascii::blank
                , i
                );

        return 0;
}
