0.9.0 does not compile with g++-2.95; it does with g++-3.3.5

[Guest]

I noticed this on my Debian testing box (x86).
There were problems with USE_ZIPIOS
I suggest to test this in the configure file.

To test what in the configure file? Sorry, I'm not sure to understand what you are suggesting. Disabling zipios support when the compiler is g++ 2.95? Disallowing compiling with g++ 2.95? Or another suggestion?

Testing the version of g++ would be enough I guess.
This may not be a minimum requirement though.
The problem was in line 504 ... of filesystem.cpp:

doing again ./configure --prefix=... ; make
with g++-2.95 first in my path yields:

To compile the CVS code, my previous automake
(Debian stable version) failed.

I installed automake-1.9 (Debian testing) and it
worked.

It could be useful to mention the minimal version
required, or to test for it.

The .tar.gz file is distributed with a working set of configure files. They are not in the CVS repository though. Consequently, if you are building from CVS, you will need autoconf (>= 2.59) and automake (>= 1.9).

Some time ago Wesnoth moved from 2.95 to later versions. There were a whole raft of problems at the time for me until the Mac GCC was updated. So this discrepancy has been known for a while.
