[ECOS] errno bug

Hi, I get folowing error while trying to use stdio.h

In file included from  
D:/SAM7/ecos/system_small_install/include/cyg/libc/stdio/s
tdio.inl:66,
                  from

                  from src/main.c:22:
D:/SAM7/ecos/system_small_install/include/errno.h:71:34:

How did you configure eCos?

a. there's no such thing as a "standard" eCos configuration.  Do you
    mean the default (template)?  or what?
b. if you want to include stdio and friends, don't include the eCos
    internal file (<cyg/error/errno.h>).  If the code needs that file,
    it will include it automatically.
