                                 Binding BIND

I downloaded BIND 8.2.3 [1] and in poking around the source code, found the
offending code [2] that prevented the parsing of DNS zone files in a certain
format. It was a one line modification to fix the problem:

-----[ C ]-----
bind/src/bin/named/db_load.c:1594

#ifndef BIND_UPDATE
static
#endif
int
getnonblank(FILE *fp, const char *src, int multiline) {
       int c;

       **multiline = 1;  /* hack to fix --spc */**
       while ((c = getc(fp)) != EOF) {
               if (isspace(c)) {
                       if (c == '\n') {
                               if (multiline)
                                       lineno++;
                               else
                                       goto eol;
                       }
                       continue;
               }
               if (c == ';') {
                       while ((c = getc(fp)) != EOF && c != '\n')
                               ;
                       if (c == '\n') {
                               if (multiline)
                                       lineno++;
                               else
                                       goto eol;
                       }
                       continue;
               }
               return (c);
       }
       ns_info(ns_log_db, "%s:%d: unexpected EOF", src, lineno);
       return (EOF);
eol:
       ns_error(ns_log_db, "%s:%d: unexpected end of line", src, lineno);
       /* don't ungetc(c, fp); as the caller will do this. */
       return(c);
}
-----[ END OF LINE ]-----

Sigh.
