dnl Some things are no longer configurable:
dnl - SMALL{TeX,MF,BibTeX}: too painful to maintain the separate patch
dnl   files, and, for TeX, texmfmem.h would have to be fixed to support
dnl   more than 256 fonts.
dnl - NONASCII: necessary for the character translation feature.
dnl - REGFIX: modern compilers mostly ignore register declarations, anyway.
dnl The code for these things remains (where applicable), so you can
dnl get these features if you are willing to hack the sources.
