older gcc (3.2) gives (false?) warning, because -Werror is set,
gdb cannot be build.

Actually, GDB releases used to ship with --disable-werror by default, which I
think is a good idea. GDB 6.8 uses -Werror by default, but I think that was an
oversight.
So, to get GDB 6.8 to build for you, please configure with --disable-werror.
Sorry for the inconvenience

thank you for your very quick reply!
I used the search (http://sourceware.org/bugzilla/) before and searched for
"infcall" but got no reply.
Could it be that the search engine is broken?
(It was just this one (1) single warning,
so I fixed it as below simply by adding = 0,
so I think this warning could be fixed anyway,
might be better than disabling warnings,
just because of beauty :))

There's a typo in the other bug's synopsis :)
I'll fix that.
