Definitely 1).  If a string constant is being passed to a function, 
then that function's parameter should be decalred "char const*".

I remember *someone* submitting a patch for this, but it was bogus, 
because it replaced the string constants with heap-allocated copies 
of the strings (instead of just changing the function parameter 
declarations).

Just let me know the functions (and parameters) for which this is an 
issue (there probably aren't many of them), and I'll fix them.
