Doesn't happen for anybody else...

I'm wondering about a buggy compiler.  The code involved is much too
simple to be broken: it's repeated calls to this:

static void
AddAcl(char *aclbuf, const char *keyword)
{
    if (*aclbuf)
        strcat(aclbuf, ",");
    strcat(aclbuf, keyword);
}

If *aclbuf contains zero on entry, then why isn't the strcat overwriting
instead of appending?  Looks like a compiler bug to me.  What is "-fast"
and does the problem go away if you don't use it?
