In C the const modifies the type. So "const char *section_name" means
"section name is a pointer to const characters" -- that is, the
characters cannot be modified via the "section_name" pointer.
In this case const is probably borderline useful.
In other parts of gdb, where used[*], it serves both a documentation
purpose and as a barrier against coding mistakes.
[*] It isn't extremely widely used since gdb predates the existence of
const.

No worries.
