# m4 depends on lex which depends on m4.  Jeeze, gimme a break!  To break
# this loop we manually lex tokenizer.l and installed it in the source
# tree as manual_tokenizer.c.  Now we can build m4 without needing lex.
#
# To regenerate manual_tokenizer.c rename manual_tokenizer.c to tokenizer.l
# and manual_tokenizer.o to tokenizer.o, build, copy tokenizer.c from the
# obj dir to manual_tokenizer.c here, and then adjust the Makefile back to
# using manual_tokenizer.c.
#
# A pox on whatever idiots who thought making lex depend on m4 was a good
# idea.  m4 is such a piece of crap, nobody should be using it anymore.
