For at least one of them, I would be surprised of the contrary.
Anyhow, that's not the main point :-)

Well, of the two points I raised one concerns documentation only (and
I didn't think it required much effort) and the other one was
something I asked because g++ 2.95 doesn't have the new iostreams. I
just wanted to know if the issue was discussed before and whether I
could expect a suitable macro to be defined in the future or not. Now
I know the answer to the second question is no :-)


P.S.: As to g++ versions, does someone know if this is correct?

#if defined (__GNUC__) && __GNUC__ <= 2 && __GNUC_MINOR__ <= 95
 #define HAS_OLD_IOSTREAMS
#endif

Or, maybe, just this?

#if __GNUC__ < 3
 #define HAS_OLD_IOSTREAMS
#endif


Thanks,
Genny.
