It was in "make bootstrap".

Now I've built again (without a bootstrap) and I got (there is only
one "Dumping under names" in the logs):

I also get the "Pure space overflow" warning from
`fancy-splash-screens-1':

On a 32 bit host (same source tree) I get:

,----[ 32 bit ]

| emacs:0:Pure Lisp storage overflow (approx. 1343128 bytes needed)

No, I didn't know.  And I don't know why these numbers are so low on
my machines.  How can I investigate?  Will it cause problems?

Bye, Reiner.
