I'm having trouble getting

working under windows 7 mingw32. I have read the instructions with that download,
and find that key scripts just don't want to work.  I have also become aware
of the instructions at

which claims that gcj inside windows can be done
 
 
-Is there a simple set of commands I can use to get my compiler download
built and working?
 
Can someone please help?

Well, I can't help directly, since I've no experience with GCJ (I'm
only using C/C++) but the page you linked to gives fairly detailed
instructions on getting it running.  Have you tried following these?

You can set up a dual boot with Linux very easily, and I think that
would be the easiest approach if you don't have access to a separate
Linux machine.

GCJ on Linux

[Me Myself and I]

Does gcj on Linux give the option to compile for windows?

Can someone tell me what the appropriate windows switch is?

I have a 64 bit Linux OS install.  IS there a 32 bit compile switch, and does anyone know it?

No.  GNU/Linux and Windows have entirely different, incompatible
runtime environments, you can't just say "I want this to run on
Windows" and expect a GNU/Linux compiler to link to the Windows
runtime.  You'd need a cross-compiler targeting Windows, as described
at rmathew's document that you've been posting, which would need
copies of all the Windows runtime files (i.e. the binaries for
"mingw-runtime" and "w32api")

Assuming you're talking about x86, it's -m32, as documented in the GCC manual.

Maybe it would be easier to just run normal Java code on Windows,
instead of compiling to native code with gcj.

You realise you also need gcc-core-4.6.2.tar to use that tarball, right?

If that's the only file you've downloaded you only have the
java-specific parts of GCC, but you need the actual compiler itself.

RE: Please, there now has to be someone who can get this working!

[Me Myself and I]

I have downloaded 

gcc-core-4.6.2.tar
gcc-java-4.6.2.tar

I have found that the both contain a directory named

gcc-4.6.2       107 Mb
gcc-4.6.2       151 Mb

What do I name what, and what should I do from here to
build the gcc (presumably first), followed by my gcj?

You don't name anything, just unpack them into the same directory and
follow the instructions at http://rmathew.com/articles/gcj/bldgcj.html
(and http://gcc.gnu.org/wiki/InstallingGCC for more general
instructions)

GCJ will be built as part of GCC, you don't build it separately afterwards.

The full process of building GCC is documented at
http://gcc.gnu.org/install/ which you apparently haven't read, despite
spending several days insisting someone must be able to help you,
because downloading the sources is described at
http://gcc.gnu.org/install/download.html and you don't even seem to
have got that far yet.  You should really all read those docs first.

RE: Please, there now has to be someone who can get this working!

[Me Myself and I]

I understand that with this arrangement, and these sorts of commands,
I am building a Native Compiler for C,C++ and Java

#-----------------------------------------------------------
$PWD/../gcc-4.6.2/configure --prefix=/opt/gcc-4.6.2 
make
make install
#-----------------------------------------------------------



-Do I gain Java Tiger 1.5 Syntax support with the file versions I have used?
-I am doing this inside mingw32.  What directory should I specify by --prefix,
and should I specify this same directory inside my /etc/profile PATH variable
initialisations?
