Binary package hint: gcc-4.5

the binary built with 4.4 and run with 4.5's libstdc++ shared library fails:

#include <tr1/regex>
# include <cassert>
# define VERIFY(fn) assert(fn)

// Tests the value() function of the regex_traits<char> class.
void test01()
{
  bool test __attribute__((unused)) = true;
  std::tr1::regex_traits<char> t;
  VERIFY( t.value('7', 8) == 7 );
  VERIFY( t.value('7', 10) == 7 );
  VERIFY( t.value('7', 16) == 7 );
  VERIFY( t.value('9', 8) == -1 );
  VERIFY( t.value('9', 10) == 9 );
  VERIFY( t.value('9', 16) == 9 );
  VERIFY( t.value('d', 8) == -1 );
  VERIFY( t.value('d', 10) == -1 );
  VERIFY( t.value('d', 16) == 13 );
}

int
main()
{
  test01();
  return 0;
};
