    headers: Implement _ISOC11_SOURCES macro when __POSIX_C_SOURCE defined

    When _ISOC11_SOURCES is defined for glibc at the same time
    __POSIX_C_SOURCE is defined, it extends the __POSIX_C_SOURCE definition
    by exaclty what C11 adds to the spec for each system header.  We follow
    both OpenBSD's and glibc's convention by also C11 or higher compliation
    mode is selected.

    The Open Group is working on issuing a new version of the POSIX standard
    that will realign the standard from C99 to a newer version of C. This
    commit is a stop-gap measure for greater compatibility until that
    environment has been standardized.
