   Hi, 

	   Thank you for your replay to my previous query about the YACC
   "feature" in DJGPP. 

	   Almost every one suggested BISON. 

	   So I tried BISON. But I still have difficulties to compile my
   program with Bison. 

	   According to the O'Reily' s book on YACC and LEX, bison produce a
   filename.tab.c file unlike YACC which produces a 
   y.tab.c file. I noticed that in DJGPP 2.0, the bison generates a file
   filename_tab.c after I run bison -y -d filename.y.  

	   For my particular case, my YACC file name is grammar.y, and the
   bison in DJGPP 2.0 produce a file called "grammar_.c" if I just type "bison
   -y -d grammar.y ".   There is no any error message. 

	   Yet if I directly use makefile, I noticed that bison generates a
   y_tab.c and y_tab.h, and the make process determined with 
   an error of " ***[grammar.y] error -1" at line "mv -f y_tab.c grammar.c"

	   What I have done wrong ?

No you just appear to not have a copy of the UNIX mv utility to move/rename a 
file.

	   The differences between my unix version and DJGPP  version are the
   file names, which appears in both makefile and 
   the ".c" files due to the change of the name of header files.
