The new section of code in lexer.ll at lines 786-801 entitled "avoid silly 
flex induced gcc warnings" causes a problem when compiling with flex-2.5.27.  
The problem lies with the three statements:

	(void)yy_start_stack_ptr;
	(void)yy_start_stack_depth;
	(void)yy_start_stack;

These are member-variables of a class called yyFlexLexer and are defined in 
<FlexLexer.h>.  But (at least in flex version 2.5.27), their visibility is 
protected.  So, "avoid silly flex induced gcc warnings" cannot see them, and 
thus produces a make error: undefind symbol first used... blah blah blah.

My solution for compilation is to comment out this section of code, but I felt 
you should know of the situation to create a proper fix before the next 
stable release.
