Please help: Unresolved getdtablesize while building snmpd.exe with MS .Net (MSVC7.1)

Dear List,

I am following the instructions from README.win32 to build net-snmp
5.1.3.1<http://5.1.3.1>with MSVC
7.1 (MS Development Environment 2003). I am building from the Workspace 
files. So far I am able to build all the libraries and application 
executables except for snmpd.exe. 
As you can see from the logs below, the linker couldn't resolve function 
getdtablesize(). 

I understand the problem is that getdtablesize() is not a Win32 library 
function; but I couldn't find any useful information from google or the List 
on how to resolve it. Any help from the List will be greatly appreciated.


TIA,


-Donghai Ma
