 Hello

 I'm working with Boost on Borland® Developer Studio for Microsoft®
 Windowsâ„¢ Version 10.0.2288.42451 and I encounter this error :

 Error E2029 enable_if_does_not_work_on_this_compiler<void> must be a class
 or a structure previously define

 In the file enable_if.hpp at line 100

 template <class Cond, class T = detail::enable_if_default_T>
   struct enable_if : enable_if_does_not_work_on_this_compiler<T>
   { };

 As you can see Borland can't use SFINAE and so used the part of the code
 which doesn't use it. But even in a new projet without any code, only
 #include <boost/filesystem.hpp> the error happen. I found nothing on the
 web about it, so if you know the problem I will be glad to know it.

 Thank you.
