Casting is almost never the right solution.

And here it's for a good reason: file_name is not to be modified, or
more importantly, freed.  You need another (const char*) variable which
contains what will be passed to _hurd_exec_file_name.

Also, you can use just asprintf instead of computing the size and then
calling snprintf.
