Description
Since 0.9.0, scummvm no longer builds with gcc 2.95. It would be nice if this was restored.
See http://sourceforge.net/tracker/index.php?func=detail&aid=1602835&group_id=37116&atid=418820 for a partial build log that shows the error.

I have the necessary changes in my local source to be able to compile with GCC 2.95.
I haven't committed it because I am not that happy with the workaround I had to introduce to properly initialize the String::_storage member. Basically, the "_storage()" statement in the String constructor results in the following warning :
warning: common/str.h:99 ANSI C++ forbids assignment of arrays
In that case, GCC won't emit code to initialize the array, hence why I do it explicitly in the patch.
Has anyone here a better workaround/idea ? Max ?

That warning regarding ANSI C++ seems bogus to me (and it does not appear with GCC 4.x nor 3.x). Since it is just that (a warning), I'd tend to simply ignore it.
As for the hashmap.h change: Please try the attached alternate patch -- does that resolve the error for you ? It certainly does so for me on a test machine.
Finally, the engines/saga/actor.cpp change could simply be commited right away :-).

I was probably unclear about the String::_storage warning. Let me try to re-phrase it. If we ignore that warning (ie. we don't change the code in the constructor and let the "_storage()" call as it is now), then _storage won't be properly initialized/cleared.
hashmap patch is ok under gcc2.95, and definitly better than the previous #if block :)

I see your point regarding class String now. Well, I am not too happy with that mod, from a "style" point of view. But from a purely pragmatic point of view, it shouldn't cause any harm, and is small enough. I'd say, add a short comment stating why we init the string like this ("Init _storage member explicitly for GCC 2.95.x compatibility" or so), and then you can commit it.

Committed.
ScummVM should now compile and execute successfully with GCC 2.95.x (a lot of warnings subsist during compilation, but it should be safe to ignore them). Closing item.
