[Coin-discuss] Compilation error

[Laszlo Ladanyi]

I have fixed the problem (I believe :-) and committed the change. Only two
headers need to be changed, both needed to '#include <cstdio>'. Quite
frankly, I have no idea why the newer g++ versions don't complain. Now
it compiles (at least clp unitTest builds fine) with g++-2.95 on Debian. 

BTW, Ted, on Debian (testing or unstable) just do 
    apt-get install gcc-2.95 g++-2.95 gcc-3.4 g++-3.4 gcc-4.0 g++-4.0 gcc g++
and you'll have all three versions. Seems to coexist quite nicely for me.
