You will find that some programs that compiled with earlier gccs do not compile any more. The fixes are simple, but if you don't care about gcc 4, you probably don't want the mess, however small it is. Be WARNED, gcc 3.3- and gcc 3.4+ do not generate binary compatible C++ code. So a library/program compiled with g++ 3.3 cannot use a program/library compiled with g++ 4.0 This is the source of the C++ transition that Debian now undergoes. I have no idea about the implications of gcc 4 for Java code. Unless you use gcj, probably none. I've switched my system (testing) to gcc 4 and had no problems with it. You can always use alternatives to keep gcc 3.3 as your default.
