Re: Dillo and Irix

Having thought about it probably too much over the past however many days,
I haven't thought of a good reason not to stick it all in an ifdef like

#if defined(__sgi)
         /* IRIX does not conform to C99; if the entire argument did not fit
          * into the buffer, n = buffer space used (minus 1 for terminator)
          */
         if (n > -1 && n + 1 < ds->sz - ds->len) {
            ds->len += n;      /* Success! */
            break;
         } else {
            n_sz = ds->sz * 2;
         }
#else
         if (n > -1 && n < ds->sz - ds->len) {
            ds->len += n;      /* Success! */
            break;
         } else if (n > -1) {  /* glibc >= 2.1 */
            n_sz = ds->len + n + 1;
         } else {              /* old glibc */
            n_sz = ds->sz * 2;
         }
#endif

and be done with it.
