        Hello, Adam!
        Hello, Cygwin hackers!

You are right - it doesn't work. But the gnustep's libobjc either!
In fact I had to add some lines into libobjc.def just to get 
gnustep-base copiled. This particular ones:

        objc_condition_allocate
        objc_condition_deallocate
        objc_condition_wait
        objc_condition_broadcast
        objc_set_thread_callback
        __objc_msg_forward

But for both libs (std GCC's and GNUstep's) I obtain error like this:

    m.AllocationBase 0x614C0000, m.BaseAddress 0x614E0000, m.RegionSize
    0xFD000, m.State 0x1000
    d:\Temp\doc\objc\test\shared_obj\ix86\cygwin\gnu-gnu-gnu\Test.exe:
    *** Couldn't reserve space for cygwin's heap (0x614E0000 <0x470000>)
    in child, Win32 error 6

search through cygwin malinglists didn't clarify the problem :-(
Any ideas?
            Thanx, Ildar.
