I thought I would post this to the list, because it's nice to have 
complete dicussions for archive reasons.

All programs in standard C++ should have a function called main 
(sometimes this function has a different name, for example in windows 
GUI programming I believe it is called WinMain). This is the function 
which is called when your program starts, and so must be present. I 
suspect you are perhaps coming from a java background and may be 
misunderstanding program structure in C++. This is however unrelated to 
cygwin, so will not be discussed further. You perhaps need to go and get 
a book or guide to c++?
