No functional changes. Deleted comments that were change notifications and
commented-out code. Made sure that setting PROGMAKEDICT,
PROGMAKESUFFIXFLEX or PROGLEMMATISE has the effect of neutralizing irrelevant code. Only if all three are defined, all code is compiled, creating a Swiss Army Knive that can
(1) Create a built-in dictionary
(2) Create an old-style flex rule list (Use the program affixtrain for new
style!)
(3) Lemmatise a text.
