!    It is particularly important that this function, rather than
!    <function>free()</>, be used on Microsoft Windows.  This is because
!    allocating memory in a DLL and releasing it in the application works
!    only if multithreaded/single-threaded, release/debug, and static/dynamic
!    flags are the same for the DLL and the application.  On non-Microsoft
!    Windows platforms, this function is the same as the standard library
!    function <function>free()</>.
