Help! "--tag " option problem.

[정운교]

Hello.
I'm tring to build gcc3.2 with "--enable-languages=c,c++,java --enable-libgcj" options on Cygwin.

When bohem-gc module is to be built, there comes the error msg below.
How can I fix it?

-----------------------------------------------------------------------------
/bin/sh ./libtool --mode=compile /cygdrive/d/gcc/gcc-3.2/gcc/xgcc -B/cygdrive/d/gcc/gcc-3.2/gcc/ -B/usr/local/i686-pc-cygwin/bin/ -B/usr/local/i686-pc-cygwin/lib/ -isystem /usr/local/i686-pc-cygwin/include -DSILENT=1 DNO_SIGNALS=1 -DNO_EXECUTE_PERMISSION=1 -DALL_INTERIOR_POINTERS=1 -DJAVA_FINALIZATION=1 -DGC_GCJ_SUPPORT=1 -DATOMIC_UNCOLLECTABLE=1  -I. -I../../../gcc-3.2-src/boehm-gc  I../../../gcc-3.2-src/boehm-gc/include   -I././targ-include -I./../../../gcc-3.2-src/boehm-gc/./libc/include -g -c ../../../gcc-3.2-src/boehm-gc/allchblk.c
libtool: compile: unable to infer tagged configuration
libtool: compile: specify a tag with `--tag'
make[3]: *** [allchblk.lo] Error 1

By the way, is there anyone who ever tried build 'libgcj' in Cygwin environment (and succeeded)?
If any, plz let me know the way.. 

Thanks.
