# If you don't have yacc, byacc, or bison or just don't want to run any of

# If you don't have lex or flex, then make target "no_lex" and leave
#	*_comp.l alone.  $(VMS)lev_lex.h will be used to work-around some
#	suspect code included in the distributed copies of *_lex.c.
# If you do either of the above, the corresponding value of YACC and/or LEX

#	Each "munged" copy should be identical to its original if no #module
