Are you sure that program.c have a correctly declared "main" function? The

The generic name of the language, but C++ is a super-set of C.

C as described by the ANSI, that means standard C. Is the most supported, 
normally the packages add more functionallity to the standard. If you really 
want to port your program to almost any machine you must follow the standard.
