/**
* When building a library, it is a good idea to expose as few as possible
* internal symbols (functions, objects, data structures). Not only does it
* prevent users from relying on private portions of the library that are
* subject to change without any notice, but it can have performance
* advantages:
*
* - It can make shared libraries link faster at dynamic-load time.
* - It can make internal function calls faster by bypassing the PLT.
*
* Thus, the compilation should by default hide all symbols, while the API
* headers will explicitly mark public the few symbols the users are permitted
* to use with a PUBLIC tag. We also define a HIDDEN tag, since it may be
* required to explicitly tag certain C++ types as visible in order for
* exceptions to function correctly.
*
* Additional complexity comes from non-POSIX-compliant systems, which
* artificially impose a requirement on knowing whether we are building or
* using a DLL.
*
* The above commentary and below code is inspired from
* 'https://gcc.gnu.org/wiki/Visibility'
