    This uses double negation and is close to unreadable.

    A kernel include file that defines an interface to a user space program
    should be self containing (that means that all includes for all non-standard
    types should be done inside these include files). Whether or not C-99
    types are used or not is less important than to use type definitions written
    in clean C so compilers other than gcc may use them.

    I recommend you to install Sun Studio and to try to compile star or cdrtools
    using Sun Studio by calling "make CCOM_suncc".

    ftp://ftp.berlios.de/pub/star/alpha/
    ftp://ftp.berlios.de/pub/cdrecord/alpha/

    You may need to hand edit the file incs/<arch-dir>/{xconfig.h!rules.conf}

    in order to enable the auto-disabled features.

    In any case, self reading the error messages from Sun Studio helps more than
    trying to discuss it.
