gperf: Compile issues with CVS GCC

[Bruce Korb]

Hi,

The output language is apparently not up-to-snuff enough for -std=gnu99:

$ /home/gnu/proj/gcc-main/_i/bin/gcc -std=gnu99 -g    gperf.c   -o gperf
gperf.gperf: In function 'gperf_find':
gperf.gperf:65: warning: 'wordlist' is static but declared in inline function 
'gperf_find' which is not static
gperf.gperf:14: warning: 'gperf_hash' is static but used in inline function 
'gperf_find' which is not static
gperf.gperf:18: warning: 'wordlist' is static but used in inline function 
'gperf_find' which is not static
gperf.gperf:21: warning: 'wordlist' is static but used in inline function

$ /home/gnu/proj/gcc-main/_i/bin/gcc -g    gperf.c   -o gperf
gperf.gperf: In function 'main':
gperf.gperf:13: warning: initialization discards qualifiers from pointer target 
ty

In case this helps, the command to create gperf.c:

gperf --language=ANSI-C -H gperf_hash -N gperf_find --null-strings \
      -C -E -I -t gperf.gperf > gperf.c

and the input is pretty simple:

%{
#include <stdio.h>
%}
struct gperf_index { char const * name; int const idx; };
%%
first, 1
second, 2
third, 3
fourth, 4
%%

I won't bore you with all the output.  The part at issue is:


#ifdef __GNUC__
__inline
#endif
const struct gperf_index *
gperf_find (register const char *str, register unsigned int len)
{
  enum.....

  static const struct gperf_index wordlist[] =
    {
      {(char*)0}, {(char*)0}, {(char*)0}, {(char*)0},
      {(char*)0},
#line 8 "gperf.gperf"
      {"third", 3},
#line 7 "gperf.gperf"
      {"second", 2},
      {(char*)0}, {(char*)0}, {(char*)0},
#line 6 "gperf.gperf"
      {"first", 1},
#line 9 "gperf.gperf"
      {"fourth", 4}
    };
