This is correct. I myself resolved the identical error in Debian's
package linux-ftpd with an almost identical patching. It is the common
origin in netkit-ftpd that is the cause. The variation uses

     #ifdef __STDC__
             va_start(ap, fmt);
     #else
             va_start(ap);
     #end

in two passages.
