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').
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.
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.

// Initial glob-exports mean that all the contents of all the modules
// wind up exported, if you're interested in writing platform-specific code.
// FIXME (#2006): change these to glob-exports when sufficiently supported.
