	Hang your head in shame - but don't feel bad for too long, since we
were all in your shoes, once-upon-a-time. :-)
	`y.tab.h' is the output of yacc invoked with the -d option to produce
a define file for token names; a `y.tab.h' file would almost never be
distributed with source code, as it is intended to be created by yacc at the
time of compilation.  You will also discover that `y.tab.c' is also missing;
this file is the C-language output file of yacc, and is created when yacc is
executed.
	If you examine the makefile, you will see that all that is needed
to produce y.tab.c and y.tab.h is to execute the command `make y.tab.c';
this automatically invokes yacc.  Many people write a makefile to explicilty
invoke yacc upon first time execution; this author did not, for whatever
reason - so it requires a separate invocation of make.
