RE: ftpcmd.y -- syntax error

[Jacques Dejean]

Hello Hans,

I discovered yesterday that the problem is with 'bison -y'.  I ran 'bison -y
ftpcmd.y' and got errors.  If I either remove the equal sign (=) from the
syntax or enclose it in quotes ('='), 'bison -y' will compile ok; however,
the final executable (ftpd) will refuse connection.  I changed 'bison -y' to
'yacc', and it worked successfully.  The final executable 'ftpd' works as
expected.  What is the difference between 'bison -y' and 'yacc'?  Isn't
"bison -y" supposed to function as 'yacc'?

You should probably have '=' or "=" in your grammar line 197. In the latter
case, you need a declaration like
  %token ASSIGNMENT "="
and your lexer should then return the token ASSIGNMENT when it detects a =.
