Version number misery

[Carlo Wood]

Grrmbl,

as if it isn't hard enough for me already that you guys
changed the signature of basic_filebuf three times in
the past months - it seems that __GLIBCPP__ wasn't updated :/

Actual changes of signatures:

Yet, my cvs update on 2001-05-17 of , I still have:

#define __GLIBCPP__ 20010417

However, the version number (1.4.4.1 versus 1.12) and actual
snapshot releases confuse me.  So if someone can enlighten me.
How can I make sure that using any snapshot my application will
use the correct signature?

Hopefully __GLIBCPP__ will *always* be a date?  Then I can use
#if __GLIBCPP__ > 20010417   etc.

PS #define _GLIBCPP_VERSION "2.91"
   Doesn't look correct either.  I suppose this comes from
   libstdc++-v3/acinclude.m4:
   AM_INIT_AUTOMAKE(libstdc++, 2.91)
   But then why was there a cvs tag libstdc++_2_92 added
   a month(!) ago?
