1. Don't use LDFLAGS="-s" if you want to debug the binary; "-s" strips
the debugging information.
2. Don't use -O if you want to be able to step through function
bodies. When optimisation is enabled, the compiler will re-order
statements and re-arrange expressions, resulting in object code which
barely resembles the source code.

That's due to 1 above.
