Hi Charlie,
Yes, I also build GEOS quite often with VC++ 8.0.
Latest problem is caused by that round function which is not
available in VC++.
Besides that VC++ does not support this function, it's not C++
standard function. ANSI/ISO C++ does not list [1] it as supported 
function from C library. Second, not all features from C are supported 
by C++ by default ;-)

BTW, here I ask about round on MSDN forums
http://forums.microsoft.com/msdn/showpost.aspx?postid=260134

[1] Standard for Programming Language C++ (working draft), Apendix C:
"7 - The C++ Standard library provides 209 standard functions from the C 
library, as shown in Table 102.$"

And the Appendinx C does not include round in Table 102. So, it's not 
supported by C++.
