- Jim pointed out problems porting yacc to DOS because of 16 bit integers,
- limits of 64K bytes in malloc, etc. I don't know exactly when we should
- declare pre-386 machines dead, but when we can, we can use 32 bit flat
- addressing models for porting such programs, as has been done for GNU
- emacs, gcc, bison, TeX/LaTeX, dvips, ghostscript, etc. Some of these have
- non-386 versions, but some notably do not, and the 386 versions are
- generally faster and offer more capacity since they breakthe 640K bytes
- barrier. Anyway, if people want a yacc for DOS and they have 386 or 486
- machines, I suggest bison.
