What about this node name?

@c Node name preserved for backwards compatibility; the correct
@c terminology is ``variable length array''.
@node GNU C Variable-Size Arrays
@subsubsection ISO C Variable Length Arrays
@cindex variable length arrays

Should I change it, potentially invalidating hyperlinks?

The node name is quite visible even in the HTML version.
