Please correct me if I'm wrong, but GCJ seems to ignore the flag in 
version 3.4.4 (minGW original build). Not implemented? So for a windows 
user not too much of help. I still get a bunch of compile-time errors 
while compiling swt.jar :

with:

gcj --version
gcj.EXE (GCC) 3.4.4 (mingw special)
...

Please, can someone advise how to deal with this issue with this version 
of gcc/gcj? It seems like some people are able to compile it. Currently, 
I would be happy to work with v. 4.x but can't because of all the win32 
problems in it... Have to fall back to the latest workable.

Thank you!!!

Michael.
