Bug in replacing strndup

Replacing libc function strndup during building of Bison 2.3 doesn't
work quite right; if the configure script determines that libc has
non-working strndup, then lib/strndup.o defines symbol `strndup' while
other .o files refer to symbol `rpl_strndup', and compilation halts with
this message:

../lib/libbison.a(xstrndup.o)(.text+0x5): In function `xstrndup':
.../bison-2.3/lib/xstrndup.c:35: undefined reference to `rpl_strndup'

# if defined (__STDC__) || defined (__cplusplus)
int yyparse (void *YYPARSE_PARAM)
# else
int yyparse (YYPARSE_PARAM)
  void *YYPARSE_PARAM;

#else /* ! YYPARSE_PARAM */
#if defined (__STDC__) || defined (__cplusplus)
int
yyparse (void)
#else
int
yyparse ()

  int yystate;

Re: bison 2.1 inserts extraneous semicolon in yyparse definition


This is fixed in more recent versions of Bison, the latest one being  
2.3.  Thanks!
