There is nothing special about vsvars32.bat. If you execute it before your  
first program (maybe inside a .cmd that calls vsvars32 and then your  
program) then all the spawned programs will already see those settings. No  
need to invoke it over and over.
Also, if you enter the same settings in the registry (so they become  
persistent) you don't have to worry again.
