Building a large program from a number of defferent source files is 
generally a good thing. It is also not covered very much in most C 
trianing courses and books. This is a shame as it seems to be assumed 
that programmers can workl out all the details for themselves and that 
is rarely true.

You could do worse that have a look at this site:

http://acc6.its.brooklyn.cuny.edu/~rbharpaz/cis15.htm

which contains course notes advanced C programming. Start with the link 
to 'writing larger programs'

this page:

http://www.network-theory.co.uk/docs/gccintro/

give some details about how to turn all those separate source files back 
into a single program.

Source files tend to contain functions that are in some way related. For 
example, you may gather all the functions that deal with a particular 
data structure together in one source file. Since you are likely to be 
the only person who knows what function is related to what, it is 
unlikely that any automated tool could do the job for you.
