I will check the syntax.
The *s++ statement may need a parenthesis to make the order of dereferencing and iterating on s explicit for the compiler. My intuition is that the statement is correct as is.

Closing stale issue. Related to implementing #8 , and not core to program. Reopen, if makefile support is being developed.
