    maint.mk: catch more abuse of HAVE_DECL in syntax-check · a363f4ed
    Eric Blake authored
    Libvirt had a patch that attempted to do:
    +#elif defined(SIOCSIFLLADDR) && defined(HAVE_STRUCT_IFREQ) && \
    +    defined(HAVE_DECL_LINK_ADDR)
    but which was not flagged by the syntax checker as suspicious
    (all HAVE_DECL_* symbols defined by autoconf are always defined
    after including <config.h>, although they are sometimes defined
    as the value 0).  Now that code is flagged until changed to:
    +#elif defined(SIOCSIFLLADDR) && defined(HAVE_STRUCT_IFREQ) && \
    * top/maint.mk (sc_prohibit_defined_have_decl_tests): Relax regex.
