Summary:  Buffer overflow in flex scanner

Original Submission:  The scanner of epsilonc, currently written in C with 
Flex, sometimes dies with a buffer overflow error. This will be fixed when 
epsilonc will be rewritten in epsilon.

The problem is probably in the machinery which implements interface 
importations.

A temporary fix is to modify flex, substituting an higher value for 
INPUT_BUF_SIZE. Note that it's defined in more than one place.

The problem has been observed on some (some) GNU/Linux x86 boxen. It has never 
been observed on PowerPC and UltraSparc.
