I wonder why I can't reproduce it.  Hm.  The xft/harfbuzz thing
shouldn't interfere here, should it?  That's a bitfont?

I tried 

./configure --with-xft --without-harfbuzz

and the CENT SIGN was of the same size as the ASCII characters, and

./configure --without-xft --with-harfbuzz

...

Hang on, the latter gives me

  Does Emacs use HarfBuzz?                                no

but just ./configure gives me

  Does Emacs use HarfBuzz?                                yes

Sounds like a bug in the autoconfig stuff.

Anyway, I get the same result there:
