State-Changed-Why:
    I will tell you precisely why you got that error but you will have to
    figure out how it happened to you and correct for it (since this is
    a local install problem not a general problem).
    Your installation is somehow using the system's base <stdarg.h>
    from /usr/include instead of the one provided with gcc.  For example,
    when I preprocess your code, I see:
    
    [...]
    # 1 "/usr/local/beta-gcc/lib/gcc-lib/i386-unknown-freebsd4.8/3.4/include/stdarg.h" 1 3 4
    [...]
    
    I get your exact error message, if compile like this:
    gcc32 -O3 -isystem /usr/include  -c t.c
    t.c: In function `bar':
    t.c:8: `va_start' used in function with fixed args
    t.c:8: `va_start' used in function with fixed args
