[svn-r4473] Purpose:
    Code cleanup for better compatibility with C++ compilers
Description:
    C++ compilers are choking on our C code, for various reasons:
        we used our UNUSED macro incorrectly when referring to pointer types
        we used various C++ keywords as variables, etc.
        we incremented enum's with the ++ operator.
Solution:
    Changed variables, etc.to avoid C++ keywords (new, class, typename, typeid,
        template)

    Fixed usage of UNUSED macro from this:
        char UNUSED *c
    to this:
        char * UNUSED c

    Switched the enums from x++ to x=x+1
Platforms tested:
    FreeBSD 4.4 (hawkwind)
