ARGV_const_t is defined the way it is for compatibility with exec*(), which expects "char *argv[]" arguments, as explained in eg https://pubs.opengroup.org/onlinepubs/9699919799/functions/exec.html Since that const mismatch is inherently unfixable, fix the place that we can - the pointers to string literals in our structs - and cast away what we cannot hope to fix.
Capital .C is sometimes used for C++ which this file certainly is not...
This allows macro tricks to match the type, avoiding the need to cast.
