Yes, sorry, this went wrong.

the only intended change was:

•                 h->storage = STORE_MMAP;
  

•                 h->newstorage = STORE_MMAP;

Peter,

IMHO, this check in does more than the log message suggests; among others, it appears to me as if this check in undoes some fixes coancerning *.new files that Sjoerd recently checked in.

Could you please check and comment whether this was/is intended? Or was there any CVS related "accident"?

Given that also the copyright statement is reverted to a state of last year, I suspect that an old version of this file has been re-activated, possibly instead of using CVS commands to revert or replay a former check in?

Thanks in advance!

Stefan
