#10793: Compilation errors in Visual Studio 2013 with /Za (disabled extensions)
------------------------------+------------------------
 Reporter:  adam.f.badura@…   |      Owner:  lcaminiti
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  scope_exit
  Version:  Boost 1.57.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------
 Use of Scope Exit generates compilation errors in Visual Studio 2013
 (version 18.00.31101 for x86) if `/Za` option (disabled language
 extensions) is used.

 I haven't checked other VS versions. I haven't checked previous Boost
 versions. And `/Za` is not set by default (language extensions are enabled
 by default).

 With `BOOST_SCOPE_EXIT_ALL` we get following errors:

 With `BOOST_SCOPE_EXIT` we get following errors:

 Note that in case of `BOOST_SCOPE_EXIT` we also get warning C4003. And it
 shows in clean build (without `/Za`) as well.
