 You're compiling in C89 mode I imagine.

 Yes, you're quite right... sorry. For some reason I thought that ISO 
 amendment 1 (i.e. 1994) would be the default :(  (Never assume and 
 all that...)  I didn't think that the default would be set so far 
 back! After all 1994 is all of 9 years ago and I'd have naively 
 thought that the dust would have well and truly settled on any issues 
 with that amendment by now -- ?
 
 While I'm writing, is there any sense for 'gcc --version' to also 
 output the default version of the language(s), as I presume this 
 occasionally changes. At some point, surely, you'll bring the default 
 up to a more recent standard...?

Why is __STDC_VERSION__ not defined? I've tried this in gcc 2.96 & 3.1:


#include <stdio.h>

#if defined __STDC_VERSION__
  #define avail "yes!"
#else
  #define avail "nope"
#endif

int main()
{
  printf( "__STDC__ == '%d'\n", __STDC__ ) ;
  printf( "Is __STDC_VERSION__ defined: %s\n", avail ) ;
}


and it results in:


__STDC__ == '1'
Is __STDC_VERSION__ defined: nope
