No idea. Can you run the command via strace or gdb to obtain more
information?

No idea here; does the lex documentation explain this message?

This might be a flex extension; try adding:

	#ifndef YY_NULL
	#define YY_NULL 0
	#endif

to the top of mapcalc.l (anywhere between the %{ and get_input_string()).
