Mea Culpa... I was just looking for the script!
Anyway, here's the whole sad saga... I logged the console output as
well, but it's quite large. If there are any parts of it that might be
important, or if you'd like the whole thing mailed as an attachment,
just let me know.
I checked out gcc with the following command:
 svn checkout svn://gcc.gnu.org/svn/gcc/trunk gcc
I've run "svn update" a couple of times from inside the "gcc" directory.
My directory hierarchy looks like this:
 src
 compile
 gcc (created by the svn checkout command)
 objdir (created by me)
I attempted to compile based on the directions in
<http://gcc.gnu.org/java/build-snapshot.html>. The exact command I used
was:
 cd objdir
 (../gcc/configure --enable-threads=posix --prefix=/opt/gcc
--enable-shared --enable-languages=c++,java && make bootstrap && make &&
make install) 2>&1 | tee compile.log
uname -a reports:
