* \brief Makes an alias name for exported function or variable.
*
* This macro is useful in cases of long mangled C++ names. For example some `void boost::foo(std::sting)`
* function name will change to something like `N5boostN3foosE` after mangling.
* Importing function by `N5boostN3foosE` name does not looks user friendly, especially assuming the fact
* that different compilers have different mangling schemes. AliasName is the name that won't be mangled
* and can be used as a portable import name.
*
*
* Can be used in any namespace, including global. FunctionOrVar must be fully qualified,
* so that address of it could be taken. Multiple different aliases for a single variable/function
* are allowed.
*
* Make sure that AliasNames are unique per library/executable. Functions or variables
* in global namespace must not have names same as AliasNames.
*
* Same AliasName in different translation units must point to the same FunctionOrVar.
*
* Puts all the aliases into the \b "boostdll" read only section of the binary. Equal to
* \forcedmacrolink{BOOST_DLL_ALIAS_SECTIONED}(FunctionOrVar, AliasName, boostdll).
*
* \param FunctionOrVar Function or variable for which an alias must be made.
* \param AliasName Name of the alias. Must be a valid C identifier.
*
* \b Example:
* \code
* namespace foo {
* void bar(std::string&);
*
* BOOST_DLL_ALIAS(foo::bar, foo_bar)
* }
*
* BOOST_DLL_ALIAS(foo::bar, foo_bar_another_alias_name)
* \endcode
