290000 is the smallest that works, with or without --with-pgtk

This is built from git checkout of emacs-30 or emacs-30.0.91 in
/home/mark/Stuff/emacs

I did some more experiments and found that my original build commands
fail but the first suggested one
in INSTALL.repo works.

Fails:
git clean -fdx
make bootstrap -j12
./configure --with-webp
make -j12

Works:
git clean -fdx
make -j12 configure="--with-webp"

However, the first way does work if there are no 'configure' options.
Any option to configure causes a failure.

no, only if there are no options

Thanks for your help.
