Summary: Sword2 engine won't compile with older g++

Initial Comment:
Main reason I'm reporting this is that unless you
massage some files by hand, this is pretty critical
combined with bug #793762. If fixing that is deemed
sufficient to fix breakage, by all means feel free to
ignore this report ;)

When using at least g++ 2.95.4 to compile scummvm, the
sword2 engine will not want to build. This problem
doesn't occur in at least g++ 3.0.4. As per
scummvm-20030823.tar.bz2 (but also earlier versions)
the error is:

g++ -Wp,-MMD,"bs2/.deps/anims.d2" -O -Wall
-Wuninitialized -Wno-long-long -Wno-multichar
-Wno-unknown-pragmas -g -pedantic -Wpointer-arith
-Wcast-qual -Wcast-align -Wconversion -Wshadow
-Wimplicit -Wundef -Wnon-virtual-dtor -Wno-reorder
-Wwrite-strings -fcheck-new -Wctor-dtor-privacy 
-DHAVE_CONFIG_H -DUNIX -I. -Icommon -I/usr/include/SDL
