POSIX:2001 (= Base Specifications Version 6) is available online at 
http://www.opengroup.org/onlinepubs/007904975/nfindex.html

sysexits.h is not contained there, therefore a fortiori it is not part
of ISO C either.

Also I'd really like to avoid code with Berkeley copyright in gnulib. While
the clause 2 in this copyright may be acceptable for glibc, it'd be a
major annoyance to start keeping track of "does GNU XY's documentation
acknowledge the BSD copyright" for various packages XY. Maybe you can
produce a sysexits.h yourself, based on some freely available documentation
on the web, and by getting the common BSD values through a program looking
like

    ...
    printf("#define EX_USAGE %d\n", EX_USAGE);
    ...
