+# NOTE: by default, you don't need to run $(LEX) and $(YACC)
+# to rebuild lex_yy.c and y_tab.c, since these will be copied
+# from the doslex.c and dosyacc.c files. So, normally you
+# don't need to uncomment the following lines.

# Replace lex with flex if you run into compilation
# problems with lex_yy.c. See also note about LEX_SCANNER
# above.
