from 2.330nb2 (upstream: 2.33) to 2.340 (upstream: 2.34).
Upstream changes from 2.33:
2.34 Thu May 23 11:30:34 CEST 2013
- work around bugs in perl 5.18 breaking more than 100
widely used modules, without a fix in sight because
p5pers don't care about CPAN anymore.
- when canonicalising, only allocate up to 64 hash key
pointers on the stack. for larger hashes, use the heap,
to avoid using too much stackspace.
- discuss the problem with setlocale (reported by a few victims).
