Hmm.  My guess is that you don't have --enable-debug in your set of
configure options?  It is not unusual to have this one enabled for GCC
even on production systems, and the size of the libs is impacted in
this case with your patch.

I've confirmed that. How about a new header unicode_norm_hashfunc.h which would include unicode_norm_table.h at the top. In unicode.c, we can include one of these depending on frontend or backend.
