/**
 * 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'
