Update of /cvsroot/monetdb/MonetDB5/src/mal In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv12770/mal
Modified Files: mal_box.mx Log Message: insertToBox copies its 2nd and 3rd arguments, so it can declare them as const. Nevertheless we still need a cast, because char * != str.

This is actually pretty useless. You've declared val as a const, not what val point to (i.e. the chars that make up the string). Consider this:
typedef char *str; void foo(const str x) { *x = 0; }
this is valid code and will be accepted by both gcc and icc, but this is exactly what you try to prevent from happening when you declare a parameter const char *. In other words, val should be declared as const char *val, and then you shouldn't need the case when calling the function.
