unable to compile with gnome libs

[Stephane Rosa <stephane sgi com>]

Hi,

it sounds like I can't compile with gnome support. I found this out
when trying to configure fvwm, which tries to compile this
(in ./configure):

#line 5911 "configure"
#include "confdefs.h"

#include <gnome.h>
int main(int c, char **v) {
   /* we can't really run this outside of X */
   if (!c) gnome_init("test-app", "0.0", c, v);
      return 0;
}


and there is a conflict between stdio.h and gnomesupport.h which
redefines sprintf and vsnprintf as if they weren't part or standard
include files already :


configure:5921: sgifwcompile -e -q -nostdinc -I.

          .h").

  extern int    vsnprintf(char *, ssize_t, const char *, /* va_list */ char *);
                ^

a more straightforward compile command gives the same result :

cc -I/d3/myroots/proot/usr/freeware/lib32/gnome-libs/include
-I/d3/myroots/proot/usr/freeware/include
-I/d3/myroots/proot/usr/freeware/include/gtk-1.2
-I/d3/myroots/proot/usr/freeware/include/glib-1.2
-I/d3/myroots/proot/usr/freeware/lib32/glib/include -o conftest -c conftest.c

Here are the offending prototypes :

stdio.h:
extern int  snprintf(char *, ssize_t, const char *, ...);
extern int  vsnprintf(char *, ssize_t, const char *, char *);

gnomesupport.h:
/* Maximum chars of output to write is MAXLEN.  */
int snprintf  (char *, size_t, char *, ...);
int vsnprintf (char *, size_t, char *, va_list);


just wanted to know if anybody already encountered such a
problem, cuz I have no clue where to look at in the first
place. Any ideas ? Why aren't they "extern" in gnomesupport ?
Can I just fix gnomesupport.h ( I guess not...)


Thanks!
Stephane
