Why do I receive a linker error "LNK1181: cannot open input file 'odbc32.lib'" when trying to compile a MEX file with Microsoft's Platform SDK on Windows 64-bit using MATLAB 7.7 (R2008b)?

When I execute the following in MATLAB:

mex rainflow.c

I get the following error:

 LINK : fatal error LNK1181: cannot open input file 'odbc32.lib'

   C:\PROGRA~3\MATLAB\R2008b\BIN\MEX.PL: Error: Link of 'rainflow.mexw64' failed.

 ??? Error using ==> mex at 213

 Unable to complete successfully.

The file 'odbc32.lib' is not included in the 64-bit installation of the Platform SDK (Microsoft Windows Server 2003 R2 Platform SDK Web Install). To work around this issue, you will need to exclude this library from the linker command, to do this:

1. Execute the following command to open the MEX options file in the MATLAB editor:

edit(fullfile(prefdir, 'mexopts.bat'))

2. Search in the file for the entries 'odbc32.lib' and 'odbccp32.lib' and remove them from the LINKFLAGS variable.
