Not really, no. The C ABI doesn't change much (or at all), certainly not on platforms that anybody actually uses. Breaking the C ABI torpedoes everyone on that platform, so it changes very rarely indeed. GCC generally does it only when a bug is found in its compatibility with the native compiler, and FreeBSD's native compiler *is* GCC, so it should never change at all (modulo bugs). Even the C++ ABI is very nearly stable now.
