"Unexpectedly", I found/made some time, and fixed the flex issue "properly": - The tar-ball releases come with the bison/flex generated tools, hence, configure only needs to check for the respetive tool when compiling the CVS sources. - Pathfinder's configure (when compiling the CVS source) check's the flex version, and quit's in case it's 2.5.31, suggesting to install/use 2.5.4 or 2.5.33 instead.

I just checked this with flex 2.5.31 on my 64-bit Fedora Core 4 desktop, and I get the same problems as on Debian;
I.e., this indeed seems to be a general problem with flex 2.5.31 and our pathfinder lexer code.
hence, unless we can fix our pathfinder lexer code to work properly with flex 2.5.31, we should indeed make configure check for the flex version, and quit once we find flex 2.5.31.
Hi Stefan,
thanks for clarifying this. Reading your original checkin message, I thought that this was a *compilation* problem, which apparently it is not.
The error message is strange. We haven't experienced any problems on that end so far, and I suspect this is really a flex problem/bug. So a ./configure check I guess is the right "solution".

P.S.: Stefan, much like you, I won't find time to look into this for at least a week. Whoever looks into this first just lets the other know, ok?
