* Bindings for libc.
*
* We consider the following specs reasonably normative with respect
* to interoperating with the C standard library (libc/msvcrt):
*
* * ISO 9899:1990 ('C95', 'ANSI C', 'Standard C'), NA1, 1995.
* * ISO 9899:1999 ('C99' or 'C9x').
* * ISO 9945:1988 / IEEE 1003.1-1988 ('POSIX.1').
* * ISO 9945:2001 / IEEE 1003.1-2001 ('POSIX:2001', 'SUSv3').
* * ISO 9945:2008 / IEEE 1003.1-2008 ('POSIX:2008', 'SUSv4').
*
* Note that any reference to the 1996 revision of POSIX, or any revs
* between 1990 (when '88 was approved at ISO) and 2001 (when the next
* actual revision-revision happened), are merely additions of other
* chapters (1b and 1c) outside the core interfaces.
*
* Despite having several names each, these are *reasonably* coherent
* point-in-time, list-of-definition sorts of specs. You can get each under a
* variety of names but will wind up with the same definition in each case.
*
* See standards(7) in linux-manpages for more details.
*
* Our interface to these libraries is complicated by the non-universality of
* conformance to any of them. About the only thing universally supported is
* the first (C95), beyond that definitions quickly become absent on various
* platforms.
*
* We therefore wind up dividing our module-space up (mostly for the sake of
* sanity while editing, filling-in-details and eliminating duplication) into
* definitions common-to-all (held in modules named c95, c99, posix88, posix01
* and posix08) and definitions that appear only on *some* platforms (named
* 'extra'). This would be things like significant OSX foundation kit, or
* win32 library kernel32.dll, or various fancy glibc, linux or BSD
* extensions.
*
* In addition to the per-platform 'extra' modules, we define a module of
* 'common BSD' libc routines that never quite made it into POSIX but show up
* in multiple derived systems. This is the 4.4BSD r2 / 1995 release, the
* final one from Berkeley after the lawsuits died down and the CSRG
* dissolved.
