[Slackbuilds-users] Mumble gtav plugin compile error on Slackware 32-bit

[KB_SBo]

Hello

Seems there was some sort of omission or regression (or "Who still uses 
32-bit?") when the gtav plugin is compiled for mumble.  This was fixed 
previously in mumble-master but somehow did not end up in mumble-1.4.287

I've posted the fix to my branch for the next update.  However, other 
than a qemu VM (not set up for audio), I'm not able to test fully.

Subject: [PATCH] FIX(positional-audio): Force 8 bytes alignment for
  CCameraAngles in GTAV plugin

https://en.cppreference.com/w/cpp/language/alignas

This fixes compilation when the implicit alignment is not 8 bytes.

It can be the case with 32 bit targets.
