Bison 1.29b bugs

[Hans Aberg]

Bison 1.29b:

I just got one implicit conversion warning this time:
  Warning : illegal implicit enum conversion from 'int' to 'token_e'
  lex.c line 326   unlexed = token;

Also, when I first compiled with "require prototypes", I got the following
error:
  Error   : function has no prototype
  main.c line 120   lex_free ();

I tried to fix this by adding to main.c:
  #include "lex.h"
but this generated other errors. So I merely turned the "require
prototypes" off (in which case the C compiler does not care if the
functions are used correctly).
