#4068: Borland also needs private/public workaround in boost::exception
--------------------------+-------------------------------------------------
 Reporter:  niels_dekker  |       Owner:  emildotchevski
     Type:  Patches       |      Status:  new           
Milestone:  Boost 1.43.0  |   Component:  exception     
  Version:  Boost 1.42.0  |    Severity:  Problem       
 Keywords:                |  
--------------------------+-------------------------------------------------
 Borland/CodeGear currently won't compile boost::exception, because it
 cannot deal with the friend declarations of exception_detail::set_info,
 inside the boost::exception class definition. So please consider applying
 the attached patch. It leaves the data of boost::exception public, when
 {{{__BORLANDC__<=0x621}}}, just like you did for other compilers.

 Note: I have no idea whether the workaround is still needed when
 {{{__BORLANDC__>0x621}}}. It's just that I only tested
 Embarcadero/CodeGear C++ 6.21. But older Borland versions certainly have
 the same problem.  For example,

 bin-v2-libs-exception-test-all_hpp_test-test-borland-5-9-3-debug.html
 says:
