Problems compiling GCC 3.4.3 and libgcj

[Daniel Kent <kentd at ufl dot edu>]

Hello,

I am working with a host / target machine setup. The cpu arch is 
the same on both, x86_64 (athlon64), the only real difference is 
size, ie. my host has a 80GB HD, my targets have 1GB compact flash 
disks (need this for mechanical vibration reasons). I have CentOS 
3.4-x86_64 fully installed on my host, and my target machines have 
the same OS just with a much smaller package list.

I am trying to get GCC 3.4.3 compiled into a relatively small 
footprint (< 200 Mb), so I can use it on my targets. I only want 
c, c++ and java installed. I downloaded the gcc-core .tar and ran 
the make and make install on that and successfully installed it on 
my target machine, taking up approximately 40MB. When I build the 
core along with c++ and java, my libraries such as libgcj.a come 
out to be over 100MB! Compared to a 20MB libgcj on my Fedora 3 
machines.

I've tried compiling with different explicit options such as: 
--enable-shared, --disable-static, --with-arch=athlon64, and a 
whole bunch of others. Nothing I've tried gets the size of the 
libgcj.a file down, nor the other big libraries. Any help or 
insight would be greatly appreciatied. Thanks.
