Thanks for looking into this. I really appreciate it.

It seems you have downloaded the source. Well, when I run "make opt" on the command line, it hits this particular directive
Code:
g++   -Wall -W -Wno-deprecated -O2 -DNDEBUG -DWORDINDEX_WITH_4_BYTE  \
-c model3.cc -o optimized/model3.o
Then it throws out the following messages
Code:
NTables.h: In member function ‚:
NTables.h:48: error: ‚ was not declared in this scope
ATables.h: In constructor ‚:
ATables.h:98: error: ‚ was not declared in this scope
ATables.h: In member function ‚:
ATables.h:114: error: ‚ was not declared in this scope
ATables.h:116: error: ‚ was not declared in this scope
make: *** [optimized/model3.o] Error 1
Sad to say, I'm accessing the code through an X11 terminal, and the error messages are not displaying properly.

In both instances, I'm actually guessing that it's PROB_SMOOTH and MAX_SENTENCE_LENGTH that's causing the problems since the other pieces of code seem fairly straightforward to me.
