Don't mess with breakpoint setting.  Just start a step (press F7 
only) and see if the trace bar that highlights the current line 
lights up the line that reads main().  If you don't get an error 
message and the bar shows up, it is almost a certainty that you have 
successfully compiled with the debug code in there.

Now re-build the whole thing.  Don't do any editing at all once you 
have re-built.  Now set your breakpoint(s).  Keep in mind, that not 
all lines in your source translate as code where a breakpoint can be 
inserted.  For example, if you have the expression:

	while (1)    <-- no breakpoint allowed here
	{
		your loop

I don't believe you can put a breakpoint at the line indicated.  
There are many lines for which this is possible.

You should also probably turn off any optimizations during debugging, 
then turn them on when the debugging is done.  Make sure that 
function inlining is turned off especially.  I have never debugged 
with these things set, so it is any guess on my part how the debugger 
behaves with them set.

This is the -s switch to gcc?  You don't need that at all.  RHide 
deals very well with gcc and gdb and knows what to do in making code 
you can work with.  You might benefit by (re-)reading sections 5.1 
and espeically 5.5 of the RHide documentation, especially since the 
author took the time to write it.
