error compiling agent++v3.4.5 lib file

[Roy]

dear mailing list,

when trying to compile agent++v3.4.5 library using MS VC++ 5 
with the instructions in the FAQ (i've successfully built the snmp++ 
lib). these 3 errrors below were found... 

for the 2 "undeclared identifier" errors, WIN32 is defined in my 
preprocessor definition...

regards, roy
P.S. i'm a newbie at vc++/c++ programming and i could be doing 
something wrong...
