#10156: Error with count_if on QNX
-----------------------------------------+---------------------------
 Reporter:  Niklas Angare <li51ckf02@…>  |      Owner:  ramey
     Type:  Bugs                         |     Status:  new
Milestone:  To Be Determined             |  Component:  serialization
  Version:  Boost Development Trunk      |   Severity:  Problem
 Keywords:                               |
-----------------------------------------+---------------------------
 Some of the tests, including test_list_ptrs_binary_archive,
 test_list_ptrs_text_archive and test_list_xml_archive, fail on QNX 6.5.0
 with the following error:

 > ../boost/serialization/forward_list.hpp:55: error: no matching function
 for call to 'count_if(std::_Fwd_list_const_iterator<A*, std::allocator<A*>
 >, std::_Fwd_list_const_iterator<A*, std::allocator<A*> >,
 boost::serialization::save(Archive&, const std::forward_list<U,
 Allocator>&, unsigned int) [with Archive =
 boost::archive::binary_oarchive, U = A*, Allocator =
 std::allocator<A*>]::predicate)'

 I don't know the reason for this error. Replacing the predicate functor
 with a function solves it but isn't very elegant. However a more
 straightforward way to count the number of elements in a range is to use
 std::distance() instead of std::count_if(). The attached patch implements
 this change. The above-mentioned tests pass with the patch.
