+/**
+ * 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'
