HiTeX missing \savinghyphcodes

[Joseph Wright]

Hello all,

Testing HiTeX (currently by manually building formats), I spot that it 
is missing \savinghyphcodes. Thus with a call

     hitex -etex -ltx -ini latex.ltx

one gets an error from ibyhyph.tex during pattern loading.

\savinghyphcodes is part of e-TeX, so there could be other omissions. 
I'm not sure exactly where is best to report this, so for the present 
I'm logging here!

Regards,

Joseph
