	In fact gcc-2.95.4 is able to compile the current development source of 
povray (I also faced this gcc relic on a not-so-old-debian
release, what I shock it was...).
	Now I'm not sure how the images produced will look like  ;-)

i am not sure that there is no interference, because there happened
same error as i posted first. old gcc-versions were left on system.

installation was done in /usr/local and softlink was created:
agun@xxx:~$ ll /usr/bin/gcc*
lrwxrwxrwx    1 root     root           24 19. Apr 22:52 /usr/bin/gcc

normal configure had this failure, following configure, too:

Creating such a link is not the right way [tm] to install a new version. 
  You simply have to configure you environment to use /usr/local in 
favor of /usr (which most people have by default anyway).

Do you really need to use a custom compile of GCC - why not just use the 
latest one from Debian? I'm not sure what's in 'stable' at the moment, 
but 'unstable' has had gcc-3.2 for quite a while (and Debian unstable 
seems as stable as any other distro). A "complete upgrade" of a Debian 
system should be as simple as "apt-get update" followed by "apt-get 
dist-upgrade", assuming your apt sources are correctly configured and 
you have a decent Internet connection (otherwise you can just get a new 
set of CDs, point your sources.list to them and use the same commands).

of course "apt-get dist-upgrade" seems to be simple. i tried it in
december. and then my system was broken due package
incompatibilities: some needed packages were not upgraded so other
packages did not work. but mostly packages were upgraded without
needs.
then i burned a testing tree with jigdo. 12 cds. not with my inet
connection ;-) and what happened? installation was broken because
configuration files were written bad (no deb-installer). and of
course: depency problems with packages.
therefore i wait for the 3.1-version.
since then i try to compile by my own and try to make debs.
it is not the soft way, but increases experience.

This is very surprising in particular because it is not supposed to
understand all of the template constructs (according to what was added to
3.x compilers).  However, if you indeed used 2.95.x (and there wasn't some
obscure upgrade you didn't notice) this suggests 2.95.x can at least parse
those constructs, which is interesting - on the other hand, I wouldn't bet
on the code working correctly, if at all.

        I'll check it again.  Yet I'm pretty sure it was indeed 2.95.4
(I remember the exact number because I could not believe having < 3.2
on the Debian I tried it).  Also the same compiler flags reported in
the initial message of this thread were not supported either.  Only
I didn't check the binary carefully, such started a benchmark run on
it without waiting for completion...
        In between I've quickly installed gcc-3.3.3, so I will need to
"obscure" this one in order to revert to the old gcc for confirmation  ;-)

your hint does not take effect.

my $PATH: /bin:/usr/bin:/usr/X11R6/bin:/usr/local/bin
my ld.so.conf: /usr/local/lib \0 /usr/X11R6/lib \0 /opt/libxml2/lib \0
and link /usr/bin/gcc was left alone.

are there other hints?

another question: is this the right group for posting?

thank you
