Subject:	gcj and -mno-cygwin

I'm just a little bit confused:

Should gcj work with the -mno-cygwin option?

$ gcj -mno-cygwin --main=Hello -gstabs Hello.java -o Hello.exe
gcj: installation problem, cannot exec `jc1': No such file or directory

I found that there are no symbolic links to jc1.exe and jvgenmain.exe in 
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/ which should point to 
../../i686-pc-cygwin/3.2/. I created them but now I get a lot of 
undefined references when compiling Hello.java with -mno-cygwin:

$ gcj -mno-cygwin --main=Hello -gstabs Hello.java -o Hello.exe
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../libgcj.a(prims.o)(.text+0x517): 
undefined reference to `_impure_ptr'
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../libgcj.a(posix.o)(.text+0x23): 
undefined reference to `gettimeofday'
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../libgcj.a(posix.o)(.text+0x7a): 
undefined reference to `sigemptyset'
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../libgcj.a(posix.o)(.text+0x99): 
undefined reference to `sigaction'
efined reference to `_impure_ptr'
...

Now I guess this is intended behaviour because -mno-cygwin is not yet 
implemented for gcj 3.2. Am I right or not?
