My build was with GTK (on SUSE 9.2 GNU/Linux).

Thanks for your investigations.

It was without "bootstrap".  I've set
MYCPPFLAGS='-DENABLE_CHECKING=1'.  I use the same source tree for
x86_64 and i686 with different exec-prefix:

  configure --prefix=[...]/HEAD --with-gtk \
    --exec-prefix=[...]/HEAD-`uname -m`

I have some (minor, IMHO) local changes.  I will try tomorrow without
any local changes and report back again.

Bye, Reiner.
