Alignment problem of buffer_storage_t as function parameter in Visual Studio 2015 Win32 about restinio

[eao197]

We can make workaround similar to one from timertt library. It will work for VS2015 builds on x32/x64 platforms.

I tried replacing alignas( std::max_align_t ) with __declspec(align(8)) in the two aformentioned lines in buffers.hpp. For VS2015 Win32 builds, it chokes with exactly the same errors. VS2015 (Win32 builds) just cannot honor aligned function parameters. VS2015 (x64 builds) however always compiles fine.

I think TIMERTT_ALIGNAS_WORKAROUND in SObjectizer/timertt library should have similar problems with VS2015 Win32 builds.

Just tested on VS2017, both x86 and x64 builds work fine. So the issue is specific to x86 builds in VS2015 (and probably prior versions).

Which version of VS2015's compiler do you have?

I'm trying version 19.00.24210 now and it supports alignas and alignof keywords.
This version also compiles sobjectizer/timertt cleanly.

@binglongx, please, check out v.0.4.0.1 (or current master), it has fixes for the issue.
