// Written by J.T. Conklin <jtc@wimsey.com> 01/17/95.
// 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

// X/Open Portability Guides and Single Unix Specifications.
// _XOPEN_SOURCE				XPG3
// _XOPEN_SOURCE && _XOPEN_VERSION = 4		XPG4
// _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED = 1	XPG4v2
// _XOPEN_SOURCE == 500				XPG5
// _XOPEN_SOURCE == 520				XPG5v2
// _XOPEN_SOURCE == 600				POSIX 1003.1-2001 with XSI
// _XOPEN_SOURCE == 700				POSIX 1003.1-2008 with XSI
//
// The XPG spec implies a specific value for _POSIX_C_SOURCE.

// POSIX macros, these checks must follow the XOPEN ones above.
//
// _POSIX_SOURCE == 1		1003.1-1988 (superseded by _POSIX_C_SOURCE)
// _POSIX_C_SOURCE == 1		1003.1-1990
// _POSIX_C_SOURCE == 2		1003.2-1992
// _POSIX_C_SOURCE == 199309L	1003.1b-1993
// _POSIX_C_SOURCE == 199506L   1003.1c-1995, 1003.1i-1995,
//				and the omnibus ISO/IEC 9945-1:1996
// _POSIX_C_SOURCE == 200112L   1003.1-2001
// _POSIX_C_SOURCE == 200809L   1003.1-2008
//
// The POSIX spec implies a specific value for __ISO_C_VISIBLE, though
// this may be overridden by the _ISOC99_SOURCE macro later.

// _ANSI_SOURCE means to expose ANSI C89 interfaces only.
// If the user defines it in addition to one of the POSIX or XOPEN
// macros, assume the POSIX/XOPEN macro(s) should take precedence.

// _ISOC99_SOURCE, _ISOC11_SOURCE, __STDC_VERSION__, and __cplusplus
// override any of the other macros since they are non-exclusive.

// Finally deal with BSD-specific interfaces that are not covered
// by any standards.  We expose these when none of the POSIX or XPG
// macros is defined or if the user explicitly asks for them.

// Default values.

//
// Local port number conventions:

// When a user does a bind(2) or connect(2) with a port number of zero,
// a non-conflicting local port address is chosen.
// The default range is IPPORT_RESERVED through
// IPPORT_USERRESERVED, although that is settable by sysctl.
//
// A user may set the IPPROTO_IP option IP_PORTRANGE to change this
// default assignment range.
//
// The value IP_PORTRANGE_DEFAULT causes the default behavior.
//
// The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
// into the "high" range.  These are reserved for client outbound connections
// which do not want to be filtered by any firewalls.
//
// The value IP_PORTRANGE_LOW changes the range to the "low" are
// that is (by convention) restricted to privileged processes.  This
// convention is based on "vouchsafe" principles only.  It is only secure
// if you trust the remote host to restrict these ports.
//
// The default range of ports and the high range can be changed by
// sysctl(3).  (net.inet.ip.port{hi}{first,last})
//
// Changing those values has bad security implications if you are
// using a a stateless firewall that is allowing packets outside of that
// range in order to allow transparent outgoing connections.
//
// Such a firewall configuration will generally depend on the use of these
// default values.  If you change them, you may find your Security
// Administrator looking for you with a heavy object.

// Ports < IPPORT_RESERVED are reserved for
// privileged processes (e.g. root).
// Ports > IPPORT_USERRESERVED are reserved
// for servers, not necessarily privileged.

// Default local port range to use by setting IP_PORTRANGE_HIGH
