cannot find odbc library to link to for c program

SUMMARY:
I have written a c program that uses odbc functions, I do not know the name of odbc postgres library I need to link to on windows.

Can someone tell me the name of the library and where I can find it.

DETAILS:
To compile the program on unix I just need to link to lodbc

The final link command on unix (aix433 in this case) looks like this:
% gcc -o function_tester -L/host/f/postgresql-8.1.3/aix433/lib ceargs.o function_tester.o -lodbc -llcfdb -Wl

On windows I get the following error that indicates to me that I need a comparable odbc library to link to on windows.

% link /nologo /warn:3 /NODEFAULTLIB:libcpmt.lib /out:function_tester.exe
*.obj *.res lcfdb.lib "/libpath:d:\host\f\postgresql-8.1.3\lib" "/libpath:D:\Progra~1\Micros~1\VC98\lib"
setargv.obj commode.obj

Stop.

Other information:
The installation I am using on windows (and unix) is postgres 8.1.3.
I installed on windows using the postgresql-8.1.msi installer program.

I use nmake and cl from Microsoft visual studio to compile.
