+// Public domain.
+
+// Macro to test if we're using a specific version of gcc or later.
+
+// The __CONCAT macro is used to concatenate parts of symbol names, e.g.
+// with "#define OLD(foo) __CONCAT(old,foo)", OLD(foo) produces oldfoo.
+// The __CONCAT macro is a bit tricky -- make sure you don't put spaces
+// in between its arguments.  Do not use __CONCAT on double-quoted strings,
+// such as those from the __STRING macro: to concatenate strings just put
+// them next to each other.
+
+// GCC1 and some versions of GCC2 declare dead (non-returning) and
+// pure (no side effects) functions using "volatile" and "const";
+// unfortunately, these then cause warnings under "-ansi -pedantic".
+// GCC >= 2.5 uses the __attribute__((attrs)) style.  All of these
+// work for GNU C++ (modulo a slight glitch in the C++ grammar in
+// the distribution version of 2.5.5).
+
+// __returns_twice makes the compiler not assume the function
+// only returns once.  This affects registerisation of variables:
+// even local variables need to be in memory across such a call.
+// Example: setjmp()
+
+// __only_inline makes the compiler only use this function definition
+// for inlining; references that can't be inlined will be left as
+// external references instead of generating a local copy.  The
+// matching library should include a simple extern definition for
+// the function to handle those references.  c.f. ctype.h
+
+// GNU C version 2.96 adds explicit branch prediction so that
+// the CPU back-end can hint the processor and also so that
+// code blocks can be reordered such that the predicted path
+// sees a more linear flow, thus improving cache behavior, etc.
+//
+// The following two macros provide us with a way to utilize this
+// compiler feature.  Use __predict_true() if you expect the expression
+// to evaluate to true, and __predict_false() if you expect the
+// expression to evaluate to false.
+//
+// A few notes about usage:
+//
+//	* Generally, __predict_false() error condition checks (unless
+//	  you have some _strong_ reason to do otherwise, in which case
+//	  document it), and/or __predict_true() `no-error' condition
+//	  checks, assuming you want to optimize for the no-error case.
+//
+//	* Other than that, if you don't know the likelihood of a test
+//	  succeeding from empirical or other `hard' evidence, don't
+//	  make predictions.
+//
+//	* These are meant to be used in places that are run `a lot'.
+//	  It is wasteful to make predictions in code that is run
+//	  seldomly (e.g. at subsystem initialization time) as the
+//	  basic block reordering that this affects can often generate
+//	  larger code.
+
+// Delete pseudo-keywords wherever they are not available or needed.
+
+// The __packed macro indicates that a variable or structure members
+// should have the smallest possible alignment, despite any host CPU
+// alignment requirements.
+//
+// The __aligned(x) macro specifies the minimum alignment of a
+// variable or structure.
+//
+// These macros together are useful for describing the layout and
+// alignment of messages exchanged with hardware or other systems.
+
+// "The nice thing about standards is that there are so many to choose from."
+// There are a number of "feature test macros" specified by (different)
+// standards that determine which interfaces and types the header files
+// should expose.
+//
+// Because of inconsistencies in these macros, we define our own
+// set in the private name space that end in _VISIBLE.  These are
+// always defined and so headers can test their values easily.
+// Things can get tricky when multiple feature macros are defined.
+// We try to take the union of all the features requested.
+//
+// The following macros are guaranteed to have a value after cdefs.h
+// has been included:
+//	__POSIX_VISIBLE
+//	__XPG_VISIBLE
+//	__ISO_C_VISIBLE
+//	__BSD_VISIBLE
