Here are some things left to do.  If you would like to contribute, send
mail to me (kb@mail.tug.org) first.

* Give TeX more options: 
  output filename:lineno: msg on error
  change prompt from `\n*' (for simpler cut-and-paste)

* Have bibtex -verbose print full pathnames.

* Make TeX--XeT a configure-time or runtime option?

* Deal with the configure tests that prevent cross-compilation:
  - Remove use of schar (in dvicopy, mf, pktogf, and tangle).
  - Learn endianness at runtime, include both Big and LittleEndian
    versions in code, call appropriate one.
  - Figure out what to do about the sizeof long test.

* Reallocate memory arrays as needed instead of just allocating once at
  the beginning.

* Possibly use spiff when doing the triptrap comparisons, so acceptable
  differences can be eliminated.
  
* Make web2c handle fields correctly, i.e., to put the field identifier
  in the symbol table of the type, instead of the global symbol table. 
  This would simplify the GFtoDVI change file a fair amount.

* Make web2c handle variant records.  This would make the TeX, Metafont,
  and GFtoDVI change files all simpler.
