[antlr-interest] compiling output

[ronald.petty at milliman.com]

If Antlr produces a lexer/parser, is it ok to expect it will compile 
without errors?  I am probably doing something wrong, so here is a 
description.

Download Antrl (tar) for cygwin (v 2.7.2)
extract to c:\antlr-2.7.2
open cygwin bash
cd /cygdrive/c/antlr-2.7.2
export CLASSPATH=.
find | grep java.g
./examples/cpp/java/java.g
cp ./examples/cpp/java/java.g .
java antlr.Tool java.g
gcc *.cpp
... 
millions of lines fly by (errors)
try
gcc *.cpp >& errors
head errors
$ head errors

.....
I assume I am not using gcc correctly (assuming I didn't incorrectly use 
Antlr).

Does that sound correct?  I have never had a working lexer, so I don't 
know?

Thanks
Ron
