Hello Alexey,

You need to specify to gcj what it should do, obviously there is no
useful default setting.

If you specify `-C' the manpage says:

 -C  This option is used to tell gcj to generate bytecode (.class files)
           rather than object code.


I would expect that you get an error like this without specifying
anything:
$ gcj Foo.java
/usr/lib/gcc-lib/i686-pc-cygwin/3.3.1/../../../libcygwin.a(libcmain.o)(.text+0x7a): undefined reference to `_WinMain AT 16'
collect2: ld returned 1 exit status



Anyway, if you want to build an executable, you say s.th. like this:
  $ gcj --main=Foo -o Foo Foo.java
and to get bytecode you say:
  $ gcj -C Foo.java
