I'd guess it's the environment. The problems with unistd.h come from older versions of flex on windows machines (like the one from gnuwin32). There are two straightforward solutions I know of: 1) Install cygwin and be sure you are using the cygwin version of flex and bison, which are much more up to date. 2) Create an empty file in the $RDBASE/Code directory called unistd.h Hope this helps, -greg
