[Snort-users] Error compiling Snort

I figured this one out, with help from George.  Posting it so that I can 
find it again once I run into this issue a year from now.

The only place in the code where I saw IXDR_GET_LONG being referenced was 
in detection-plugins/sp_rpc_check.c
As far as the includes, this symbol was only defined in rpc/xdr.h (which 
George pointed out), but this file wasn't included in the snort source. 
After trying (unsuccessfully) to "#include <rpc/xdr.h>" at the top of 
sp_rpc_check.c, I just took the part where this symbol is defined in xdr.h 
and threw it into sp_rpc_check.c: "#define IXDR_GET_LONG(buf) 
((long)ntohl((ulong_t)*(buf)++))".  After that, no issues...
