When building with "clang -Wwrite-strings", the compiler complains about
initializing a char* array (variable genhomedirconargv) with literal
strings (which are in read-only memory).

However the programs needs to use a non-const char* array in order to
fake arguments of getopt_long() (called by parse_command_line()). Silent
the compiler warnings by introducing casts to char*.
