Please dont tell me it is the number of seconds since 1 Jan of 1970 GMT, cos it is not (at least not in my case!). If I pass this number to a Java program (print it using a java.util.Date() object), the result is the current...

Is there a way to keep track of a build number within a program? Essentially incrementing a #define everytime the program is compiled (at link time would be even better, though tougher to implement). something like __DATE__ or __TIME__, perhaps __BUILD__? i.e., void printVersion() const { cout << "My Program\n(build __BUILD__)\n"; }
