This functionality is built-in to the dynamic linker as part of its
support for C++ static constructors and destructors. You can make use of
this functionality with GCC's C extensions by using the destructor
attribute on your cleanup function's declaration. For example:
static void cleanup(void) __attribute__((destructor));
