gcc-3.0 pb with macro __STDC_VERSION__

[Guillaume Rumeau]

Hi, 

here a little programm that compile correctly with gcc-2.95.2
(linux-gnu-glibc-2.1) 

but not correctly with gcc-3.0 in the same architecture.

Is my installation of gcc-3.0 not correct ?

Thank you.


#include <stdlib.h>
#include <stdio.h>
#include <string.h>

int main(void) {

#ifdef __STDC__
    printf("C Version value = %ld\n", __STDC_VERSION__) ;
#else
    puts("No C version") ;
#endif
    return EXIT_SUCCESS ;
}

/*
Local variables:
mode:c
compile-command: "gcc3 -W -Wall  -c test.c"
End:
*/

Error message with gcc-3.0 
test.c: In function `main':
test.c:8: `__STDC_VERSION__' undeclared (first use in this function)

After pre-processing :

int main(void) {


    printf("C Version value = %ld\n", __STDC_VERSION__) ;



    return 0  ;
}


And after gcc-2.95.2 pre-processing :

int main(void) {


    printf("C Version value = %ld\n", 199409L) ;



    return 0  ;
}

In attached-file, the complete result of gcc-3.0 pre-processing.
