Link problems in win32.o of ns

["YangMing" <pantong@public1.ptt.js.cn>]

When I run command "nmake makefile.vc" under windows95,the LINK program reports following problems. 

-------------------------------------------- 

win32.o : error LNK2001: unresolved external symbol _gethostname@8
win32.o : error LNK2001: unresolved external symbol __imp__MessageBoxA@16
win32.o : error LNK2001: unresolved external symbol __imp__MessageBeep@4
win32.o : error LNK2001: unresolved external symbol __imp__SetMessageQueue@4
win32.o : error LNK2001: unresolved external symbol _WSAStartup@8

I don't know why LINK can't find SDK functions such as gethostname,MessageBox,MessageBeep,.

Thanks!
