Undeclared erros when buildin 4.0.6

I'm getting this error message when trying to build 4.0.6 on an x86 Linux (2.2.16 Kernel). dns.c: In function `php_if_checkdnsrr': dns.c:188: `T_MX' undeclared (first use in this function) dns.c:188: (Each undeclared identifier is reported only once dns.c:188: for each function it appears in.) dns.c:197: `T_A' undeclared (first use in this function) dns.c:198: `T_NS' undeclared (first use in this function) dns.c:200: `T_PTR' undeclared (first use in this function) dns.c:201: `T_ANY' undeclared (first use in this function) dns.c:202: `T_SOA' undeclared (first use in this function) dns.c:203: `T_CNAME' undeclared (first use in this function) dns.c:212: `C_IN' undeclared (first use in this function) dns.c: In function `php_if_getmxrr': dns.c:242: `HEADER' undeclared (first use in this function) dns.c:242: `hp' undeclared (first use in this function) dns.c:243: parse error before `*' dns.c:281: `i' undeclared (first use in this function) dns.c:281: `C_IN' undeclared (first use in this function) dns.c:281: `T_MX' undeclared (first use in this function) dns.c:286: parse error before `)' dns.c:287: `cp' undeclared (first use in this function) dns.c:288: `end' undeclared (first use in this function) I had similar problem with 4.0.5 and skipped it, but I need to update now. Can anyone tell me what's going on? I assume this build somewhere so this must be a broken or missing header? Thanks, -- Jeremy Wadsack Wadsack-Allen Digital Group
