fix handling of missing const type qualifier

For ISO C23, the function strrchr that return pointers into their input arrays now have definitions as macros that return a pointer to a const-qualified type when the input argument is a pointer to a const-qualified type.

Update to const type for variable, as returned string is only used in comparisons which const can be used
