Yes:

  http://gcc.gnu.org/install/

Quick Summary (Linux):
======================

1. Get latest GCC sources from CVS or from a recent snapshot
into a folder, say $GCC_SRC. (See http://gcc.gnu.org/cvs.html.)

2. Create a *separate* build folder, say $GCC_BLD.

3. Inside $GCC_BLD configure GCC with GCJ like so:

$GCC_SRC/configure --prefix=$HOME/mygcc --enable-languages=c,c++,java \
--disable-checking --enable-__cxa_atexit

(Assuming you want to install GCC/GCJ into "mygcc" within
your home folder.)

4. In the same folder, run "make bootstrap" and then
"make install" when that finishes. On a 2.4GHz P4 with
1GB of RAM for example, this process takes just around
an hour.

5. Add $HOME/mygcc/bin to your $PATH (before everything
else) or explicitly specify the path to the executables
to use this new, shiny, all-improved GCC.

For using the new Binary Compatibility ABI, see the
included docs as well as:

  http://gcc.gnu.org/wiki/How%20to%20BC%20compile%20with%20GCJ

??? Well, for GCJ at least, it is a good idea to try
with the latest sources from CVS as there are all sorts
of fixes and features compared to 3.4.x.
