enum_t in scoped_enum_emulation.hpp conflicts with system header <rpc/types.h>

[Matthias Troyer]

The UNIX system header <rpc/types.h> defines a macro

#define enum_t int

This clashes with the enum_t member in boost/detail/scoped_enum_emulation.hpp

As a consequence there is a compilation error in Boost.Filesystem if any of the RPC headers is included before boost/filesystem/operations.hpp

This is a regression that can easily be fixed by renaming enum_t to enum_type in boost/detail/scoped_enum_emulation.hpp

the test program is trivial:

#include <rpc/types.h> #include <boost/filesystem/operations.hpp>

(In [55604]) Fix #3346 boost/detail/scoped_enum_emulation.hpp enum_t conflict with Unix rpc/types.h

[Daniel James]

(In [59679]) Merge some detail changes.

• [53670] Avoid C style casts.
• [55604] Fix #3346 boost/detail/scoped_enum_emulation.hpp enum_t conflict with Unix rpc/types.h
• Don't foward declare containers when using gcc's parallel library and add a macro to disable forward declaration. Fixes #3866.
