building gcj on Intel Mac OS X 10.4.4 ?

When attempting to build gcj on a brand new Intel iMac running Mac OS X 
10.4.4 I get configure errors.
I tried both gcc 3.4.5 and the most recent 4.1 snapshot, 20060120.
configure complains about a bunch of systems for which the new 
i386-apple-darwin8.4.1 target is not supported:
 target-libmudflap target-libffi target-boehm-gc target-zlib target-libjava
 target-libada gnattools target-libgfortran target-libobjc
For gcj support, my guess would be that support for at least 
these is required: target-libffi target-boehm-gc target-zlib target-libjava
Is this error due to gcc's configure not understanding Apple's recent move to 
Intel chips or is there more work required, for example in boehm-gc, to 
compile an Intel-native gcj on Mac OS X ?
Is anyone working on this ?
Andi..
