You *will* get flamed if you post wrong code offered as a solution, but at
least you admit not to checking it. It is obvious that given the lines:

...

>    strings_are_same_backwards = ( s1[s1_index] == s2[s2_index] );
when s1_index == 0 first time in, the expression "s2[s2_index]" is
effectively s2[strlen( s2 )], the terminating '\0', not the last character
in the string, so this routine will only work when s1 and s2 are empty
strings.

No, people usually get flamed when they post incorrect information. A wrong
answer is worse than no answer at all.
